摘要
采用传递系数法和FLAC的强度折减法,对猴子石滑坡在天然状态、三峡蓄水及地震等工况下的稳定性进行了对比分析计算.结果表明,两种方法计算结论基本一致,但FLAC法能反映出滑坡体内的应力和应变变化规律,能跟踪关键点的位移、速度以及应力随时间的变化.
Based on the stability calculation of the Houzishi landslide by transfer cofficient methods and strength reduction methods of FLAC(Fast Lagrangian Analysis of Continua). The stability of the landslide is computed and analyzed under conditions of the nature situation, water storage of the Three-Gorges and earthquake. The result indicates that FLAC can reflect the law of changes of stress and strain in landslide ,can traceing the changes of displacement, velocity and stress of the keypoints with the time.
