小湾左岸坝前堆积体边坡稳定性分析研究
Slope Stability Analysis and Study of Deposit Body Located in Front of Xiaowan Dam on Left bank
摘要
Abstract
This paper deals with the study of the stability of the deposit body located in front of the Xiaowan dam on the left bank under different operating conditions, and of the potential instability extent of the lower part rock slope of the 2? mountain ridge where the deposit body exists. The study covers the following main items: (1) the shear strength parameter triaxial test and study of the deposit body; (2) the centrifugal model test and study of the deposit body under different operating conditions of naturally no water, water impoundment, excavation without water, and earthquake, etc.; (3) the stability 3? D non? linear finite element numerical analysis of the deposit body under different operating conditions such as naturally no water, stagnant water, water impoundment, non? impoundment induced earthquake and impoundment induced earthquake, etc.; and (4) the 2? D and 3? D limit equilibrium analysis of the deposit body slope under the different operating conditions of naturally no water, stagnant water, water impoundment, non? impoundment induced earthquake and impoundment induced earthquake.关键词
