摘要
探讨了地下洞室断面形状的优化计算方法和应用，以隧洞断面的特征尺寸为设计变量，围岩破坏区总面积为目标函数，工程要求的过流量断面面积为约束条件。用序列无约束极小化方法（ＳＵＭＴ）求解非线性有约束的优化问题。对拟建工程的隧洞进行了优化分析。成果是合理的。
A calculating method for optimizing of the cross sectional shape of a subterranean tunnel and its application have been studied in this paper. The characteristic dimension of cross section of the tunnel has been taken as the design variable, while the total failure area within adjoining rock as the objective function and the area of water carrying section required as the restraint condition. The non linear optimization problem with constraint has been solved by use of the sequential unconstrained minimization technique (SUMT). The cross section of tunnel of a proposed project has been optimized and analyzed. And the result obtained is reasonable.
