摘要
在三维离散元面-面接触刚性块体单元模型基础上,提出块体单元允许变形、断裂的一种计算模型。此计算模型不仅考虑岩块之间的节理刚度,而且考虑岩块自身变形以及岩块可能发生断裂的情况。
The deformable and rupturable block model is given for 3D distinct element method based on the rigid block model(plane to plane contact types). This method can be applied to stability analysis of rock slope,and the joints of rocks and the rupture failures in the rocks are considered. In order to justify this method and its computer program,a sample is given to show the rupture of slopes. The results of computation shows that this method is feasible and reasonable.
