| 摘 要： | 通过对岩石边坡中的裂隙水对岩石边坡裂隙作用的力学原理进行分析的基础上,提出了数值流形方法中对裂隙水渗流作用的计算方法,并在原有考虑裂纹扩展的数值流形方法程序中加入了考虑裂隙渗流的子程序。最后利用综合考虑渗流与断裂的数值流形方法程序对含初始裂隙的岩石边坡在渗流作用下的破坏过程进行了模拟。模拟结果再现了原始裂隙在渗流作用下的扩展路径及所形成的切割块体在自重作用下的运动过程,与边坡的实际破坏模式基本一致。

| Abstract: | Through the analysis of the mechanical principle of the action of crack water on the crack of the rock slope,the calculation method of the crack water seepage action by numerical manifold method is proposed.The subprogram considering crack seepage is added into the original numerical manifold method program considering crack propagation.In the end,the numerical manifold method program comprehensively considering seepage and fracture is used to simulate the failure process of rock slope with an existing crack under the action of seepage.The results re-show the propagation path of the existing crack under the action of seepage and the movement process of the block cut by the crack under self-gravity,which is in agreement with the actual slope failure mode. |
