摘　　要：卡拉贝利水利枢纽进水口塔群是在强震地区软岩地基上建造的高耸水工建筑物,工程特点鲜明。结构设计计算需要解决基础侧向抗滑、高边坡稳定、地基承载、结构抗震等棘手问题。针对这些问题,本文借助刚体极限平衡分析法和有限元方法对塔群与地基的联合作用进行分析,实现了安全的结构设计,得出了相应的规律性结论和见解,其中,等安全系数法为塔基侧向抗滑稳定计算提出了新的解决途径。The intake-tower group of Kalabeili Water Control Project is a high hyraulic structure group built on a soft rock founda- tion within a strong seimic region with distinct engineering characteristics, for which the thorny problems, such as foundation lat- eral sliding, high slope stability, foundation bearing capacity, structural seismic resistance, etc. , are necessary to be solved in the structural design. For these problems, the combined effect of the tower group and the foundation is analyzed herein by means of the rigid body limit equilibrium method and finite element method, thus the corresponding regular conclusion and un- derstanding are obtained, in which a new solving way for the calculation of the tower foundation lateral sliding stability is pro- posed with the application of the equal safety coefficient method.
