摘    要:结合黄河上某水利枢纽坝址区的地质情况,讨论在软岩地基上,尤其是有软弱夹层存在的岩石地基上修建重力坝可以考虑采取的几种方案.选取几个设计工况,对方案2的断面形式分别采用材料力学法和有限元法进行应力计算,在坝体表面和内部均未出现较大拉应力,满足设计要求.

关 键 词:软岩地基  重力坝  坝基处理  应力计算

Abstract:Combining with the geological condition of one hydraulic dam site district on the Yellow River, several scenarios are discussed how to build the gravity dam in the soft rock foundation, especially in soft interlayer rock foundation. Several design schemes are selected to calculate the stress using material mechanics method and finite element method. The results show that the second scheme can meet the design requirement, and has no larger tensile stress in the dam surface and internal.
Keywords:soft rock foundation  gravity dam  dam foundation treatment  stress calculation
