摘　　要：采用刚体极限平衡法和有限元方法对天花板碾压混凝土拱坝进行了坝肩稳定分析,以抗滑稳定安全系数对坝肩稳定进行评价和研究,分析坝体在各种工况下的稳定性。针对坝肩安全储备相对不高,有针对性地采取了稳定处理措施,提高了坝肩的整体性和安全性。The abutment stability of Tianhuaban RCC arch dam is analyzed by rigid body limit equilibrium method and finite element method respectively and evaluated by the sliding-resistance stability and safety coefficient to analyze the stability of dam under various operation conditions. For a relative lower safety margin of the abutments, the treatments for improving the stabilities of abutments are also proposed.
