用弹塑性有限元法，对碾压混凝土重力坝层面上的应力，安全系数分布和沿层面渐近失稳破坏过程进行了初步探讨，揭示了碾压混凝土重力坝的失稳破坏机理，取得了可供进一步研究碾压混凝土重力坝稳定性，提高稳定安全度的参考意见
The elastic-plastic finite element method is used to investigate the stress, the safety factor distribution and the asymptotic instability failure process of RCC gravity dam. The instability failure mechanism of RCC gravity dam is revealed. Reference for further research on stability of RCC gravity dam and its stability and safety
