遗传算法在某广场基坑中的应用

Application of Genetic Algorithm to Foundation Pit of One Square

摘要: 本文以某广场基坑支护项目为实际工程案例，对土钉墙支护结构的优化设计方案进行实证分析，在保证安全稳定的前提下，采用改进遗传算法对土钉墙支护结构进行优化设计，使用MATLAB软件中的遗传算法对支护型式进行优化设计，通过实证分析支护型式的各种参数对工程造价的影响程度，最终确定最经济合理且安全稳定的设计方案。

Abstract: This article takes the foundation pit supporting project of one square as an illustration. Optimal design of soil-nail bracing structures is analyzed by the empirical data. In condition of guaranteeing safety and stability, improved genetic algorithms to optimize the design of soil-nail bracing structures are used. Optimal designs of foundation pit support types are made by the genetic algorithm of MATLAB and the influence of parameters on the engineering cost of support types is analyzed by the statistics. Finally, the most economic and reasonable project of safety and stability is obtained.
