【摘要】 强度储备法抓住影响边坡稳定因素中最关键最难确定的强度指标，通过研究不同强度参数所对应的破坏区域的演变关系来分析边坡的稳定性和潜存的破坏机理，是切实可行的。受材料及试验水平限制，以往在该方面的研究仅局限于少数数值分析。本文结合具体边坡工程实践探索强度储备法在岩质高边坡稳定性分析中的应用。在边坡稳定性三维非线性有限元分析中用强度储备法求解边坡在各种工况下的稳定安全系数，并在三维地质力学模型试验中用该方法寻求边坡的稳定安全系数及破坏机理获得成功。数值计算与模型试验所得结果相近。研究成果在工程实践中得到成功的应用。表明强度储备法是岩质边坡稳定分析的有效方法。更多还原

【Abstract】 おhe material strength reserve method is practical in the study of the stability and failure mechanism of rock slope by analyzing the development of failure zone of different shear strength parameters of the rock mass of the slope. Limited by the material of the model test and test level, this method has so far been explored only in the aspect of numerical analysis. In this paper, in combination with with a hydraulic engineering high rock slope, application of this method to high rock slope stability analysis is studied by 3-D non-linear FEM and 3-D geological mechanical model test. The results of calculation are in accord with those of the model test and have been successfully used in the design of the slope. The strength reserve method is proved to be effective for stability analysis of high rock slope.更多还原
