【摘要】 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更多还原

【Abstract】 By means of the 3 D elestoplastic FEM, a preliminarily analysis of the distribution of stress and safety factors and the process of the failure along the bedding surface of RCC gravity dams is made, and then the failure mechanism is indicated. The result can be used as reference in further studies of the stability and engineering design of RCC gravity dams.更多还原
