Every year, tens of thousands of friends drive to the 317 or 318 Sichuan-Tibet Line, and it can be said that most of them have successfully arrived in Lhasa, but a very small number are not so lucky. So what are the main reasons for this problem? Let's organize it according to the data.
First, the weather is cloudy and uncertain The natural environment system composed of factors such as high altitude, low temperature, air moisture ratio, solar radiation intensity, geographical environment structure, etc. of the Sichuan-Tibet Line is very special, and it is very different from the plain area where we are located. 318 all the way through the past year all year round weather can be encountered, so clothing should bring four seasons.
2. Difficult and dangerous road conditions 1. Mudslides generally occur in semi-arid mountainous or plateau glacial mudslide areas. Once a rainstorm comes or the glacier thaws, the large and small stones have enough moisture to slide down the slope, forming mudslides that pour down low-lying roads, ravines, and rivers. 2. Landslides occur like avalanches, where thousands of tons of soft silt and sand slide down from towering mountains, smashing roads, instantly blocking passing vehicles and even "burying people and cars alive". If you encounter the terrain in front of you during the driving process is very steep, sediment, stones and other accumulations, there must be special care in the area with few trees, and then carefully observe the road section ahead before passing, if there is a small amount of slipped stones or mud in the front section, the buildings on the mountain are crooked, that is the precursor to the upcoming landslide here.
Third, the dilemma of traffic jam Friends who enter Tibet for the first time may not know that traffic jams on the Sichuan-Tibet line are very common! Sichuan-Tibet line tourism is the most popular season, a variety of self-driving cars, trucks, tourist buses on the Sichuan-Tibet line come and go, but the Sichuan-Tibet line in the summer rainy season, the most prone to landslide road blocking, etc., many sections of the road because of perennial landslides, the road is often smashed, many sections of the implementation of unilateral release, traffic efficiency is greatly reduced, the pass rate is very low.
Fourth, car accidents Regarding the car accidents that occurred on the road into Tibet, everyone can search for news, and there have been too many traffic accidents in Daocheng, Maoya Grassland, Anjura Mountain, Qinghai-Tibet Line, and so on. The biggest obstacle to self-driving into Tibet is the car accident, and over the years we have seen too many traffic accidents and have to give up the action of entering Tibet. So drive into Tibet slowly, abide by the traffic rules, Liya Highway Maoya Grassland Qinghai-Tibet Line these places do not drive fast because the road is good, there will be traffic accidents almost every week, do not drive fast!
The Sichuan-Tibet line is 2200 kilometers long, the Sichuan-Tibet line is not all asphalt roads, there are many sections such as Mangkang Haitonggou and Motuo Highway are full of sand and mud, and several places on the Ali Great Northern Line in Tibet, such as Tsoqin Zhari Nanmucuo, do not even have a highway, and can only follow the trajectory of the front car on the muddy grass. Once these roads are washed by rain, melting ice and snow, and eroded by the river, they have become a trap to drag the vehicle, especially in the grass on both sides of the road, in the mud, driving on the way to rest, in order not to block the back car forward or want to see the beauty more closely, the riders will often drive the car to the side of the road, the soil condition of these unknown lands no one knows who knows, in addition to the hard school off-road, who walks those grass mud roads are not good, the probability will fall into it.
Sixth, the fearful "high reaction" altitude sickness is really distressing, especially for friends who have entered Tibet for the first time. Most of the travel to the Sichuan-Tibet line will have light or heavy altitude sickness, it is recommended to eat a period of Rhodiola Rosea a month before traveling, do not exercise strenuously when reaching the plateau above 3000 meters above sea level, have a stable mentality, and do not worry too much about this problem. Regarding altitude sickness, we have an article called Sichuan-Tibet Line, this frightening physiological phenomenon on the Sichuan-Tibet Line, which should not be taken lightly, and has made a detailed strategy for altitude sickness, which is not much to introduce here. In addition, the ultraviolet rays of the plateau are very strong, so be sure to bring sunscreen and moisturizing supplies (sun hats, sunglasses, sunscreen, moisturizer, etc.) when you go out to play, so as to avoid taking off a layer of skin when you return from play.
In fact, the dilemma on the above roads is not terrible, according to the experience of a large number of donkey friends in and out of Tibet, we provide you with the following countermeasures. 1. Weather: Always pay attention to the weather conditions and real-time road conditions in front of you before and during the journey. 2. Itinerary: Formulate a flexible itinerary plan, leave alternative space and alternative roads, and flexibly adjust at any time to "change lanes". 3. Alternative route: 318 is the southern line into Tibet, and there is also a 317 northern line into Tibet, and Xinduqiao, Litang and Bonda can all change lanes from 318 to 317. 4, road conditions: pay more attention to the road conditions in front of the car, if there is gravel on the road in front of you, mud and other slippery falls, you must stop to observe the mountain situation, do not have a fluke mentality. Make roadside assistance calls if necessary; avoid driving to low-lying areas as much as possible to prevent mudslides. 5, food: high-energy snacks, easy to preserve fruit, pure water. 6. Clothes: fleece cotton, storm jacket, storm pants, outdoor non-slip shoes, high rain boots, hiking boots, sunglasses, sunscreen, sun hat, gloves, anti-crack lipstick, mosquito spray, inflatable pillow, warm water bottle, change. >> Sichuan-Tibet Line Travel Dressing Guide 7, Medicines: Cold Medicine, Gastrointestinal Medicine, Analgesic Medicine, Anti-Hyperreaction Drugs (Rhodiola Rosea, Inosine Oral Liquid, Oxygen Tablets), Glucose Powder, Quick-Acting Heart-Saving Pills, Antibacterial and Anti-Inflammatory Drugs, Vials of Alcohol Cotton Balls, Band-Aids, Disinfectant Gauze, Vitamin Effervescent Tablets, Cold Medicines, Warm Treasure Stickers. 8, communication: it is best to prepare two mobile phones (mobile and telecommunications are preferred), and pre-deposit the phone bill.
So where are the sections that must be paid attention to? 1. Dangerous Batang to Mangkang Canyon Road The Batang to Mangkang road section is a high-incidence section of accidents and needs to be paid attention to. This section of the road is basically in the canyon, and it is easy to encounter landslides in the rainy season. In addition, the surrounding river is very turbulent, and the road is often washed off, so be sure to drive carefully.
2. Narrow and dangerous Mangkang to Zuogong road section The road section from Mangkang to Zuogong road, on the scenery alone, this section is quite beautiful. It crosses the Lancang River, we go down the mountain from Lawu Mountain to the Lancang River, and then up Jueba Mountain, this section of the road is up and down, sandwiched between two mountains. From the perspective of road conditions, this section of the road needs to be taken seriously. Although it has been renovated and turned into an asphalt road, the road surface is still very narrow, very dangerous, and it is very difficult to get a car. There have been many car accidents here, you must pay attention when passing by, pay attention to the speed, and remember to honk the horn when turning. After passing through this thrilling section of the road, it is another challenge to climb dongda mountain, which has snow all year round and an altitude of more than 5,000 meters.
3. Relatively "safe" nu river seventy-two turns But when it comes to danger, everyone may have heard of the seventy-two turns of the Nu river. You may not think that this place is much safer than the previous two sections, the Seventy-two Turns of the Nu River. The reason is that the appearance here protects the safety of the walkers. The scenery of the winding road of the 72nd turn of the Nu River is very magnificent, no matter how many times you pass, you will be shocked, which is very suitable for taking pictures. Although its curves are very urgent, many tourists will slow down to take pictures when passing by here, and the speed of travel has become slower and the safety has been improved.
4. Quickly cross the Rocky Area - Nu River Gorge Section Cross the Nu River to the foot of Yela Mountain, which is the Nu River Gorge section. This place is annoying because it has so many rockfalls that we all call it the "Big Collapse Zone". But this section of the road is not a large area of landslides, but there will be stones falling from the mountain continuously. If the car is hit by falling rocks, it is not good, and the impact of the falling stones can penetrate the car at once.
When you get here, you can't stay and you have to pass quickly. The canyon road is narrow, more than 20 kilometers long, and even if you don't stop, you will still be in danger for a long time. So don't say stop and take a picture of a falling stone or something, the stone falls, if people are unlucky, they are purely looking for death. Compared with the above-mentioned 318 Sichuan-Tibet Line, the 317 Sichuan-Tibet Line is much safer. There are many tunnels on the 317 National Highway, and the previous accidents were all on the winding mountain highway (for example: Xiao la Mountain), and now there is no need to climb the mountain, and the safety factor is naturally greatly improved.
