摘　　要：结构可靠指标的计算,除采用传统的一次二阶矩法外,还可根据可靠指标的定义和几何意义,转化为求解有约束条件的优化问题。本文用MATLAB优化工具箱函数求解结构可靠指标,应用于水电站厂房结构整体稳定可靠度研究,计算简单方便。Besides using the traditional first- order second- moment method, struactttre reliability index calculation can be converted into optimization of the constraint condition based on the reliability index definition and geometry meaning. In this paper struactttre reliability index optimization calculation based on its geometry meaning is discussed, the method is recommended to be used to study reliability of hydropower station power house monolithic stability, and it is mentioned, by use of MATLAB optimization instrument box function, the calculation is simple.
