【摘要】 在地下岩体空间等复杂结构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。因而提出了采用响应面方法结合数值试验对其进行拟合，在此基础上求系统的可靠度，并将其应用于某地下尾矿库库体系统稳定的可靠性分析。更多还原

【Abstract】 Usually it is very difficult to get an analytical equation of limit state for reliability analysis of complex structure in underground rockmass space. A way is provided to fit analytical equation of limit state by response surface method and numerical simulation experiment. The reliability of system is calculated based on this method. The stability reliability analysis is made for a system of underground tailing-ore-bin by this method.更多还原
