中文摘要：
对于岩质高边坡而言,其潜在滑动面上力学参数的合理性、边坡开挖后需要的整体加固力以及计算的边坡安全系数与实际边坡安全储备的接近程度将直接影响岩质高边坡工程的安全性与经济性。从现有的确定边坡潜在滑动面力学参数的反演分析方法入手,指出其存在的局限性,提出边坡潜在滑动面力学参数最小取值准则;在此基础上,根据开挖岩体的总压力充其量是诱发边坡失稳的全部不利荷载的思路,提出边坡最大主动加固力准则。将潘家铮的上、下限原理应用于边坡的数值分析与稳定性评价,提出数值法进行稳定性分析评价的安全系数上、下限准则,并将其在工程评价中进行验证与推论。该研究可为工程设计人员进行有效经济地选择岩质高边坡加固方案提供宏观判据与基本原则。
英文摘要：
For high rock slopes,the mechanical parameters on the potential sliding surface,the reinforcement forces needed after slope excavation,and the correlation between the calculated factor of safety and actual safety margin will directly influence engineering safety and economy.Based on back analysis methods for determining mechanical parameters of potential sliding plane and their shortcomings,the minimum value criterion of mechanical parameter selection is proposed;and the maximum reinforcement force criterion is then proposed on the basis of the equivalence of the largest reinforcement force needed and the weight of excavated rock body.Finally,the upper and lower limit criteria of the numerical results used for stability analysis and assessment are put forward and applied to engineering design based on PAN Jiazheng′s upper and lower limit theory.It will helpfully provide designers with criteria of slope stability analysis and assessment on reinforcement scheme selection of high rock slope.
