| 摘 要： | 将上覆岩体视为含有不连续面（如节理等）的层状块体模型，采用离散单元数值模拟方法，研究了岩层内部直至地表的动态移动过程．根据实测资料，得到了上覆岩层从直接顶板直至地表整个范围内的移动动态关系，验证了离散单元法分析的结果．

| Abstract: | The overlying rockmass is regarded as a laminated block model with discontinuous faces (e.g.joints).Discrete element numeric simulation method is applied to study dynamic movement in the rocks up to the surface.Based on the measured data the dynamic relation of the overburden from the immediate roof to the surface is obtained,and the calculated data by the discrete element analysis are proved to be correct. |
