立洲拱坝坝肩地质条件复杂，断层、节理裂隙等软弱结构面发育，直接影响坝肩的稳定安全性。针对上述地质问题采用地质力学模型试验与有限元计算分别进行了研究，通过二者综合对比分析，得到了坝肩及抗力体表面变位分布规律、两坝肩的最终破坏形态以及整体稳定安全系数，揭示了影响坝肩稳定的控制因素及其薄弱部位，为工程的设计和施工提供依据。将物理模型与数值计算相结合，二者相互对比和互为补充，全面分析和论证拱坝坝肩稳定性。

The geological conditions of Lizhou Arch Dam Abutment are very complex ,such as faults ,joints and fissures weak struc‐tural planes .These structures lower the stability of the abutments .This paper presents an experimental study of abutment stability by using geo‐mechanical model test and finite element calculation .Through a comparison and analysis ,the features of deformation distri‐butions are obtained ,the failure modes of both dam abutment ,the overloading safety factors of dam and foundation .The controlling factors and weak regions impacting the stability of dam abutment are revealed ,and serve as a basis for engineering design and con‐struction .Physical model is combined with numerical calculation .A comprehensive analysis is made of arch dam abutment stability .
