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。
It is practicable to analyze the stability of the slope and the underlying failure mechanism by studying the evolution relationship between the failure zones corresponding to different strength parameters by using the strength reserve method to grasp the most crucial and most difficult intensity index that affects the slope stability factors of. Limited by materials and test levels, previous studies in this area have been limited to a few numerical analyzes. In this paper, concrete slope engineering practice to explore the strength of the reserve method in the stability of rocky slope analysis. In the three-dimensional nonlinear finite element analysis of slope stability, the stability safety factor of slope under various working conditions is solved by the strength reserve method. The method is used to find the stable safety factor and the failure of the slope in the three-dimensional geomechanical model test The mechanism succeeded. The results of numerical calculation and model test are similar. The research results have been successfully applied in engineering practice. It shows that the strength reserve method is an effective method for rock slope stability analysis.
