| 摘 要： | 天生桥一级水电站厂区岩质高边坡中存在影响边坡稳定的断层、顺坡向裂隙及褶皱层面。基于三维弹塑性有限元分析，采用强度储备法研究了边坡在多种工况下的稳定性及失稳破坏机理，研究成果已供工程参考应用。该边坡已经历了施工及几年汛期暴雨的考险，边坡稳定。工程实践表明：研究成果可靠，强度储备法是岩质高边坡稳定性分析的有效方法。

| Abstract: | The slope near the plant of Tianshengqiao - 1 hydropower station is affected by faults, fissures and thecommon plane of folds which all dip outside the slope. Based on 3 - D nonlinear FEM, by using strength reserve methodwhich is used to analyze the stability of the slope by step by step lowering the shear strength of the rock mass to failure,the stability and failure mechanism of the slope under different cases were studied. The research results were successfullyapplied to the design of the slope. The slope was constructed and has withstood the tests of rainstorms of several years.Engineering application indicates that the research results are reliable and the strength reserve method is effective forstability analysis of high rock slope. |
