为了更能准确地评价黄河堤防边坡的稳定性,对可靠度理论在黄河堤防边坡稳定性分析中的应用进行了研究;可靠度理论是建立在概率统计基础上的,充分考虑了土体抗剪强度参数c、φ值的变异性及其相关性等对边坡稳定的影响;利用编制的蒙特卡罗法边坡稳定可靠度分析程序进行了工程实例计算,得出的评价边坡稳定性的可靠指标比定值法得出的安全系数更能反映工程实际情况,具有极其重要的应用推广价值。
In order to evaluate the stability of the Yellow River embankment slope more accurately, the reliability theory is applied to the stability analysis of the Yellow River embankment slope. The reliability theory is based on the probability and statistics, Shear strength parameters c, φ variability and its correlation on the stability of the slope; the use of prepared Monte Carlo slope stability and reliability analysis program for the calculation of engineering examples, the resulting evaluation of slope stability The reliability index of sex can reflect the actual situation of engineering more than the safety factor obtained by the valuation method, and has the extremely important value of application and popularization.
