摘要

岩土体当中存在大量的不确定因素，给边坡的稳定性分析判断带来了困难。在分析了计算参数的不确定性是影响分析可靠性的主要原因的基础上，运用模糊集理论考虑计算参数的不确定性，提出了模糊参数的具体构造方法和边坡稳定的不确定性分析思路。该方法可以根据不同隶属度下的参数截集区间，计算出相应隶属度下的安全系数区间，并可由此得到边坡的可靠性指标和安全系数建议值。通过不同算例研究表明，使用此方法能充分考虑计算参数的不确定性，得到的安全系数更加科学可靠。

Abstract

Due to many uncertainties in the geotechnical mass

the appreciation of the slope stability is very difficult. On the basis of the conclusion that the uncertainty of the computation parameters is the main factor which influences the reliability of the stability analysis

the fuzzy set theory is used to consider the uncertainty of the computation parameters; and the constitution method of the fuzzy parameters and the idea for analyzing the uncertainty are put forward. By this way

the cut intervals of the safety factor under different membership degrees can be easily calculated according to the corresponding cut intervals of parameters; and the reliability index of the slope stability and the recommended single safety factor can be got. Different examples are studied; and it is shown that this method can fully consider the uncertainty of the computation parameters; and the obtained safety factor is more reasonable and reliable.
