【摘要】 小湾左岸坝前堆积体边坡为一复杂岩土高边坡 ,其稳定性分析中涉及到堆积体本身的稳定性及由其下部前缘基岩引起的牵引滑动问题。采用三维非线性有限元数值分析方法 ,研究了该边坡在天然无水、蓄水及地震工况下的稳定性及失稳破坏机理。研究成果为边坡设计和加固施工提供了依据。更多还原

【Abstract】 The accumulation body on the left bank in front of the dam of Xiaowan Hydro_Power Station has a complex rock_and_soil structure with high slope.Its stability is involved in itselve’s stability and the drag_sliding stability problem caused by bed_rock failure.In this paper,the stability and the failure mechanism of the high slope body is studied under conditions of empty storage,storage and earthquake by means of 3_D non_linear FEM.The result can be taken for a basis of design and reinforcing work.更多还原
