【摘要】 以岳城水库主坝为例,采用有限元法与条分法相结合的方式,对浅层滑坡坝段进行了非稳定渗流期的稳定分析,并与常规方法进行了对比.结果说明,有限元法与条分法相结合能充分考虑非稳定渗流期渗流力对土坝稳定的影响,比常规方法更符合实际情况.更多还原

【Abstract】 With the finite element method and the bishop method together,the stability of the dam reach shallow landslide is the analyzed in the period of infiltration in the case of Yuecheng Reservoir and then the mode is compared with general modes.As a result,the mode of the finite element method and the bishop method together can take the influence of the percolation force on the safety in the period of unsteady infiltration into enough account,and it accords with the fact better than general modes.更多还原
