摘要:
通过采用拟静力法和有限差分法两种方法分别对北京密云县的和尚峪尾矿库坝进行了动力稳定性分析，然后计算得到在地震荷载影响下的边坡时程安全系数，并将此处所得到的安全系数与笔者之前采用拟静力法计算得到安全系数进行对比。最后，基于陈育民开发的PL-Finn模型并利用FLAC3D对尾矿坝在地震条件下的液化区域以及液化后的大变形进行了分析。
Abstract:
The dynamic stability on the fine sand tailings dam of Heshangyu in the county of Miyun, Beijing was analyzed with the pseudo static method and finite differential method. The safety coefficient of different time on the slip crack surface under the condition of earthquake was obtained, and the safety coefficient was compared with the safety coefficient calculated by pseudostatic method.At last the large deformation of liquefaction and post liquefaction under the condition of earthquake were calculated using the software of FLAC3D by the model of PLfin designed by Dr Chen Yumin.
