摘要
洞室的间距和断面是工程设计中的两个重要问题 ,两者是相互关联的 ,用统一的设计变量表示洞室间距和断面特征尺寸 ,以围岩破坏区的总面积作为目标函数 ,按使用需求确定约束条件。结合工程实例求解这类有约束非线性优化问题 ,成果合理。
Both spacing and cross section of tunnel are two important problems in design of a project and they are correlative. The unified design variables have been used to indicate the characteric sizes of spacing and cross sections of tunnels. The total area of failure zone within surrounding rock has been set as objective function. Whereas the constraint conditions are fixed in accordance with operation requirements. This kind of non linear optimization problem with constraint has been solved in a practical project. The results are reasonable.
