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。
通過採用擬靜力法和有限差分法兩種方法分彆對北京密雲縣的和尚峪尾礦庫壩進行瞭動力穩定性分析,然後計算得到在地震荷載影響下的邊坡時程安全繫數,併將此處所得到的安全繫數與筆者之前採用擬靜力法計算得到安全繫數進行對比。最後,基于陳育民開髮的PL-Finn模型併利用FLAC3D對尾礦壩在地震條件下的液化區域以及液化後的大變形進行瞭分析。

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-liquefac-tion under the condition of earthquake were calculated using the software of FLAC 3 D by the model of PL-fin de-signed by Dr Chen Yumin .
