    摘要:

    基于虚拟仿真技术手段,开发了复杂环境作用下土的力学性质虚拟仿真实验系统。系统可通过虚拟仿真实验装置实现土样反复增湿-脱湿和低温-高温的干湿循环和冻融循环过程,模拟炎热多雨和酷暑严寒复杂环境气候对土体力学性状的影响;实现对经历复杂环境作用土样的固结、直剪及三轴试验,测试土的强度及变形特性。虚拟试验操作过程与实体试验基本相同,试验环境相似,互动感受逼真。学生可在虚拟环境中直观体验土样的环境模拟及力学试验过程,克服了实体试验中难实现、成本高昂、受时空限制等困难,在课堂教学时间内学习和认知复杂环境作用对土体力学性状的影响。

    Abstract:

    Based on virtual simulation technology, a virtual simulation experiment system of soil mechanical properties under complex environment is developed. The system can realize the repeated dry wet cycle and freeze-thaw cycle of soil samples through the virtual simulation experiment device. The influence of hot summer and rainy, heat and cold on the mechanical properties of soil can be simulated. The consolidation, direct shear and triaxial tests are carried out to test the strength and deformation characteristics of soil samples under complex environment. The operation process of virtual test were similar to that of real test. The interactive feeling was lifelike. Students can intuitively experience the process of environmental simulation and mechanical test of soil samples and overcome the difficulties of hard realization, high cost and limited by time and space. Students could understand the effect of complex environment on soil mechanical properties in limited classroom teaching time.
