市政工程深基坑支护设计优化多偏重于缩减构件尺寸和数量等直接成本,而忽视缩短工期带来的间接效益.以湖北省武汉市黄孝河CSO调蓄及强化处理设施深基坑项目为背景,详细阐明了从结构平面、支护体系、支撑体系和降排水等方面的优化思路,打破了传统"流程式"的设计思路,为深基坑支护创造敞开式作业条件,以便各专业施工作业,可从多维度节省工期,其产生的经济效益、社会效益和环境效益显著.
Optimization and Applied Research of Deep Foundation Pit Support Design in Large Municipal Engineering Project
The optimization of deep foundation pit support design often emphasizes the direct cost reduction com-ponent dimensions and quantities in municipal engineering,while neglects the indirect benefits resulting from shortened construction periods.Based on the deep foundation pit project of CSO storage and enhanced treatment facilities of Huangxiao River in Wuhan,Hubei Province,the optimization strategies were elaborated from aspects of structural planning,support systems,bracing systems and dewatering in this paper.These strategies broke the traditional"procedural"design and optimization approach.Open working conditions was created for deep foundation pit support to make it easier for each construction operation.The construction time was saved from multi-dimension,which resulting in significant economic,social,and environmental benefits.
