摘要
在大量分析影响工程岩体物理力学因素基础上,筛选出影响工程岩体c,值的主要因素。探讨了用模糊数学理论选取c,值的方法,对制约模糊分析精度的权重计算方法进行了改进,提出了基于灰色关联度理论的分析方法,与其他几种方法比较,其计算结果更符合工程实际。
The key factors influencing c (cohesion) and ψ (internal friction angle) of engineering rock masses is abstracted with consideration of physical and mechanical properties of rock masses. The selection method of c and ψ values is discussed based on the fuzzy comprehensive judgment theory and an improved weight calculating method is proposed by means of the grey relation degree. The results show that the presented method is more efficient than that of the empirical formula.
