摘要
基于剩余推力法思想 ,结合Newmark有限滑动位移法 ,考虑了由于动力作用造成的孔隙水压力变化 ,对一种最为常见的边坡灾害—滑坡 ,提出了一种简便的估算地震动力永久位移的方法。对一实例用该法和快速拉格朗日元 (FLAC3D)进行对比计算 ,结果表明两者的结果基本接近 ,前者要保守一些。
A new simpler method is presented for evaluating the earthquake-induced permanent displacements of sliding body based on residual pushing force method as well as Newmark′s method (1965). At the same time, pore pressure increment caused by dynamic force is considered. Then this method is applied to a case, in which our prediction result is very close to that obtained by using numerical method, but the value obtained by former methed is slightly higher than that by numerical method.
