摘要
介绍了概率随机可靠度计算理论中改进的一次二阶矩法及可靠度反问题计算理论。以一软岩巷道稳定可靠度的问题为例,应用可靠度反问题分析方法作了参数的计算,并对结果进行分析,表明该方法对地下软岩工程中设计参数的控制具有指导作用。
In this paper, improved first order second moment method an d reliability inverse problem theory is presented. A reliability inverse problem analysis is applied to the stability of a soft rock roadway. Numerical results are given and studied. It is conclude that this method is useful to guide the control of some primary s in underground soft rock engineering.
