摘要

基于虚拟现实思想，研制了三轴试验的计算机虚拟仿真课件。介绍了使用Authorware平台开发研制的三轴试验的计算机仿真课件以及太沙基三轴固结过程中孔隙水压力计算公式，详细论述了基于修正剑桥模型的三轴试验土样在不排水剪切过程中超孔隙水压力、应力-应变关系、有效应力和总应力的推导过程，并在课件中编程实现。通过利用课件对三轴试验进行模拟操作，不仅能使学生进行系统的试验前的操作训练，而且能够使学生更深刻地掌握土力学的基本原理。

Abstract

Based on the idea of virtual reality，A triaxial test computer simulation courseware is developed. The triaxial test courseware used Authorware software and a closed-form formula of excess pore water pressure of soils during consolidating are introduced. Based on the modified Cam clay model

the deductions of excess pore water pressure

the curve of stress-strain

the path of effective stress path（ESP）and total stress path（TSP）during undrained triaxial test are discussed. Finally

this deductions are programmed in the triaxial test courseware. Using the courseware

the students can not only do operation Training before lab test

but also grasp of the basic soil mechanic principles profoundly.
