REPONSE SURFACE METHODS FOR RELIABILITY ANALYSIS AND ITS ENGINEERING APPLICATION
-
摘要: 在岩体工程等复杂系统的可靠性分析中, 得到极限状态方程的解析表达式往往是非常困难的。本文提出了采用响应面方法结合数值试验对其进行拟合, 求系统的可靠度, 并应用于某地下岩体空间围岩稳定的可靠性分析。Abstract: It always is very difficult to get an analytical equation of limit state for reliability analysis of underground rock space. In this paper provided a way to fit analytical equation of limit state by response surface method and numerical simulation experiments is suggested, and on this basis the reliability of system is calcculated.This method is used in reliability analysis of surrounding rockmass stability of underground tailing bin.
