一种软粘土三轴流变试验的数值模拟技术

Numerical Simulation Technology of Soft Clay Rheological Test

在进行软粘土三轴流变试验有限元数值模拟时,引进了切向弹性抗力约束和位移约束关联技术对试验机与试样的接触面进行模拟,研制了相应的有限元计算程序。以上海地区某软土工程的三轴流变试验为实例,进行了有限元数值模拟计算,计算结果与试验所得结果十分相吻合。

In the finite element method (FEM) numerical simulation of soft clay抯 triaxial rheological test, the link between the constraint of tangent elastic reaction and the constraint of displacement is provided to simulate the interaction of the interface between test machine and testing soil model, furthermore, the FEM program is developed. Based on the triaxial rheological test of one soft clay engineering in Shanghai, with the approved model, the numerical simulation results is nearly corresponding to the test results.
