针对如何提高房建施工过程中的基坑开挖支护质量的问题,提出一种房建施工中结合遗传算法进行基坑开挖支护设计的方法。结合房建施工过程中的实际问题,分析基坑开挖进行支护设计时的不同要点。基于要点需求如工程质量、安全保障、可持续性以及施工质量等,提出采用遗传算法对基坑支护结构设计中的变量进行选择优化。同时构建了相应的数学模型,通过惩罚函数建立约束条件。经过进一步的仿真实验验证,从桩体下降程度、地表沉降量以及桩顶位移等关键指标进行基坑开挖支护分析。实验结果表明,结合遗传算法进行基坑开挖支护设计,能够保证基坑稳定性,把控施工成本,保证施工质量以及施工安全。

In order to improve the quality of foundation pit excavation support in the process of housing construction,a method of foundation pit excavation support design combined with genetic algorithm in housing construction is proposed.Combined with the practical problems in the process of housing construction,the different points of foundation pit excavation for support design are analyzed.Based on the key requirements such as engineering quality,safety assurance,sustainability and construction quality,a genetic algorithm was proposed to select and optimize the variables in the design of foundation pit support structure.At the same time,the corresponding mathematical model is constructed,and the constraints are established through the penalty function.After further simulation experiment,the foundation pit excavation support was analyzed from the key indicators such as the degree of pile decline,surface settlement and pile top displacement.The experimental results show that the design of foundation pit excavation support combined with genetic algorithm can ensure the stability of foundation pit,control the construction cost,and ensure the construction quality and construction safety.
