| 摘 要： | 利用二维颗粒流软件PFC 2D对砂土的抗剪强度进行研究。通过建立数值试样模型、设立相对合理参数、引用＂橡皮膜＂程序等方法对砂土的三轴剪切试验进行数值模拟,模拟的结果较好地反映了砂土的力学性质。

| Abstract: | Shear strength of sand are studied make use of the Particle Flow Code in 2 Dimensions.Through the establishment of numerical sample model,setting up relatively reasonable parameters,citing ＂rubber film＂ program and other methods to carry on the numerical simulation of the sand three-axle shear test.The simulation results better reflect the mechanical properties of sand better. |
