摘要
针对地质灾害中非连续体的变形运动特征与预测防治等问题 ,应用非连续变形分析 (DDA)方法 ,对工程地质灾害的数值模拟与预测进行了系统的研究 ,具体分析了链子崖危岩体的地质构造 ,并用DDA方法进行了危岩体在两个地质剖面的变形模拟和防治模拟 ,得出了一系列的形变位移场、应力场变化图。通过防治模拟分析 。
Aimed at the problem of character of deformation and forecasting of discontinuous blocks in geological disaster,the theory and application research has been systemically done in the side of the value simulation and forecasting on geological disaster with the discontinu-ous deformation analysis method. Particular analysis of geological structure of Lianziya is made. Deformation and control simulation have been made on two section planes of dangerous precipitous cliff, and a series of displacement field pictures are obtained. From the result, we can affirm that the deformation of dangerous precipitous Lianziya cliff has the direct relationship with the structure of the mine-out area and the T11 segment, and the simulation results are basically according to the reality.
