【摘要】 碾压混凝土重力坝采用大仓面薄层连续浇筑，其层面是一个薄弱环节，这是与常规混凝土坝的主要区别之一。为此结合仿真模型试验和非线性有限元法计算，论述碾压混凝土重力坝层面破裂面的形状、位置、发生条件及其影响因素，为设计碾压混凝土重力坝提供了科学依据更多还原

【Abstract】 Now, in the RCC gravity dams construction, large area thin layer continuous placing concrete are adopted. The joint surface is a weak link. This is a main different point from the conventional concrete ones. In this paper, through simulation test and nonliner finite element method, and by the shape, location, and conditions of the failure fracture, and influence factors of RCC gravity dam, there is a discussion in detail. It provided scientific basis for designing RCCGD.更多还原
