摘要
讨论了非均质岩体中及其加固后双线隧洞的优化方法与应用 .以洞间间距和隧洞断面的几何形态为设计变量 ,以围岩破坏区总面积为目标函数 ,按工程使用要求的断面确定约束条件 ,结合工程实际求解这一有约束非线性优化问题 ,成果是满意的 .
A review of optimization method and its application is presented. The total area of failure zones in adjoining rock is set as the objective function to optimize the spacing and cross sections of double line tunnels for water transfer project. The restraint conditions are determined in line with the cross section required according to the operation of the project.
