| 摘 要： | 海底隧道纵断面位置的选定是海底隧道设计的关键问题。针对传统设计中采用满足最小岩石覆盖厚度的方法,提出了基于GA理论的优化设计方法,可以在一组满足规范要求的初始方案中自动寻找最优解。其基本思想是首先建立纵断面初始种群,对解进行编码,然后对可行域中的可能解用评价函数进行度量,对解进行选择、交叉、变异,从而获得最优解。通过实例验证,该方法能对海底隧道纵断面方案进行优化,可以为设计提供参考,具有一定的实用价值。

| Abstract: | Profile selection is the key problem in subsea tunnel design.Minimum rock cover is the main factor that is considered in the traditional method.The paper introduces a new optimization design method which can look for the best project in a group that meet the requirements of the code.The main idea is that initial profile group is set up at first and distributing code to each project,then the possible project is evaluated,which exsits in the feasible area with function,and getting the best result with several... |
