In the field of mechanical experiments, the physical properties of soil are essential for the stability and safety of structures. The soil compression consolidation experiment is one of the basic experiments to study the compressibility and consolidation characteristics of soil, which can help engineers better understand the deformation and strength changes of soil under load. With the rapid development of science and technology, the application of virtual simulation technology in the field of education is becoming more and more extensive, especially in the teaching of mechanics experiments, the emergence of the virtual simulation laboratory of mechanics has greatly enriched the teaching methods and improved the teaching effect. In this paper, we will take the "soil compression and consolidation experiment" as an example to discuss the application and advantages of the mechanics virtual simulation laboratory in soil mechanics teaching.
I. Introduction
As one of the core courses of civil engineering, the experimental teaching of soil mechanics is of great significance for cultivating students' practical ability and innovative spirit. However, traditional soil mechanics experiments are often limited by factors such as experimental equipment, site, and cost, and it is difficult to fully meet the teaching needs. The emergence of the mechanics virtual simulation laboratory provides an effective way to solve these problems.
2. The importance of the virtual simulation laboratory for mechanics
The soil compression and consolidation test is mainly used to determine the compressibility coefficient, consolidation coefficient, consolidation index and other parameters of soil. These parameters have important guiding significance for the engineering design and construction of soil. Through the OBIER Mechanics Virtual Simulation Laboratory, students can browse the soil mechanics laboratory, operate the soil compression and consolidation experimental process, record data, and report the experiment. At the same time, the training can further improve the students' cognition of the operation process of soil consolidation and compression experiment, consolidate the theoretical knowledge learned, improve the flexibility of virtual operation, and consolidate students' understanding of the process.
3. Advantages of the virtual simulation laboratory of mechanics
The mechanics virtual simulation laboratory comprehensively uses virtual reality, distributed interactive simulation, three-dimensional modeling, network communication and other technologies to build an open three-dimensional virtual simulation training platform, simulate experimental props, and establish a series of realistic drill environments for students on the computer system that are the same as the real environment, so that students feel "immersive" in general, with a high picture impact and a strong sense of immersion and reality, so that students are like actual combat drills in the whole training process.
1. Save experimental resources
In the mechanics virtual simulation laboratory, students can simulate the whole process of soil compression and consolidation experiments through computer software, without the need for real experimental equipment and venues, thus greatly reducing the cost of experiments. In addition, mechanical virtual simulation experiments can be carried out repeatedly without worrying about the consumption of experimental materials and damage to equipment.
2. Improve the safety of the experiment
The soil compression and consolidation experiment involves high-pressure loading and other operations, which has certain safety risks. In the mechanics virtual simulation laboratory, students can conduct simulation experiments in a safe environment, avoiding accidental injuries that may occur in real experiments.
3. Enhance experimental controllability
The Mechanics Virtual Simulation Lab allows students to freely adjust parameters during experiments and observe experimental results under different conditions. This high degree of controllability allows students to have a deeper understanding of the principles of the experiment and master the skills of experimental operation.
