武汉地区深基坑支护系统方案的优化设计模型

An Optimization Design Method for Bracing Project of Deep Foundation Pit in the First Yangtse River's Terrace of Wuhan

深基坑支护系统方案的优化设计是一个相当复杂的系统工程优化问题。针对工程实际 ,采用层次分析方法 ,根据武汉地区长江一级阶地的工程地质和水文地质特点构造层次结构模型 ,建立起深基坑支护系统方案的评价体系 ,并对评价指标进行了规一化处理。通过各种可行方案的定量评价对比 ,选出最佳方案 。

It is very difficult to optimize the bracing project of deep foundation pit . By means of analytical hierarchy process method , the project evaluation system is established in accordance with engineering geological and hydrological geological conditions of the first Yangtse River's terrace . The optimal plan is selected out by appraising all the possible projects qualitatively . In the paper , the qualitative and quantitative evaluation targets are dealt with by the normalized method.
