| 摘 要： | 运用ANSYS程序对水下的岩质边坡进行数值模拟分析,采用不同的材料强度来模拟岩石和软弱结构面。应用强度折减方法对边坡的强度参数进行折减,直至边坡出现破坏,分析边坡在达到破坏时内部的应力应变情况和位移变形情况。对于波浪力,本文采用简化的波压力方程模拟低频的水波对边坡的波压力影响,并用多个模型比较计算的方法得出最佳的模型尺寸和水下荷载的计算模式。

| Abstract: | This paper analyzes the stability of rock slope with finite element method with strength reduction along weak planes.The paper uses line-graded layer mesh technique to mesh the model and uses different mechanical parameters to simulate the intact rock and joints.It further uses simplified wave pressure equation to simulate the wave pressure of the low-frequency wave loading and brings a rational model dimension and submerged loading computation scheme. |
