多目标模糊优选理论在深基坑工程方案优选中的应用

Application of the multi-objective fuzzy optimization theory in deep foundation program optimization

基坑方案的设计直接影响着基坑工程的投资规模、生产成本和经济效益的高低，也影响着施工管理方案的制定，其优化设计更是深基坑工程的重要环节。基坑设计方案受许多因素的影响，因而也需要从多个角度去评价方案的优劣。基坑设计方案的优化实质上是实现多重目标的最优，必须运用基于多重目标的模糊综合评价法去评价一个方案的好坏，即用模糊数学对受到多种因素制约的事物或对象做出一个总体的评价。本文将以武汉创世纪广场基坑工程为例，应用多目标模糊优选理论，研究深基坑工程方案的优选。

Foundation programs directly influence the investment scale excavation of the design, the level of production costs and economic benefits, but also affects the construction management program development. Furthermore, the optimum design of the foundation is the most important part of deep excavation.Foundation design is affected by many factors, so it needs to evaluate from various angles the pros and cons. The essence era foundation design optimization is achiving the optimum of multiple objectives, which must use multiple targets based on fuzzy comprehensive evaluation method to assess whether a program＇s good or bad. That is to say, it is using fuzzy mathematics to make an overall evaluation of the objects which constrained by many factors or things.This article will take Wuhan Genesis Plaza Foundation as an example and use the multi-objective fuzzy optimization theory to research the optimization of deep excavation program.
