摘要
Abstract
To solve the fuzzy random reliability of underground cavern group system,the relative displacement value and relative displacement allowable value of the perimeter of the underground cavern are regarded as the structural load and structural strength respectively,and the explicit expression of the functional function for the reliability analysis of the underground cavern is constructed.On the basis of which,the randomness of the mechanical parameters of the rock body is considered,the fuzzy nature of the allowable value of the perimeter of the cavern relative displacement is taken into account,and the probabilistic estimation technique of the network(PNET method)is adopted to solve the systematic fuzzy stochastic reliability degree of underground cavern group.Taking the cavern group of power generation system of a hydropower station as an example,the system fuzzy reliability of the cavern is calculated during the construction period by using the method and use the evolution-support vector machine method instead of the numerical method to calculate the relative displacement around the cavern,so as to obtain the system fuzzy stochastic reliability of the cavern group.关键词
