摘　　要：给出了具有圆弧型破坏面的边坡工程极限平衡分析中计算随机模糊可靠度的方法,将模糊数学的原理与可靠性理论结合起来,推导出了以模(糊事件)精(确概率)指标表达的边坡工程随机模糊可靠度公式,既考虑了岩土边坡工程材料的模糊性,又满足了稳定性定量评价的要求.The method for calculating random-fuzzy reliability in limit equilibrium analysis of stability of the slope with divcular potential sliding surface is presented. The corresponding calculation formulas are deduced by combining fuzzy mathematics with reliability theory. The random-fuzzy reliability of the slope engineering is expressed by the fuzzy （event）-exact （probability） index in the suggested method. Both the objective attributes of rock .soil mass and the quantitative evaluation of slope engineering stability are considered at the same time. The calculation formulas in the method are determinate and convenient for use.
