密集建筑区深基坑支护方案选择

Selection of deep foundation pit supporting program in dense buildings

为解决在密集建筑区施工时深基坑支护施工方案的选择问题,运用模糊数学和多目标决策的理论与方法,通过建立深基坑支护评价目标体系,综合考虑决策者对施工工艺、经济性、工期以及对周围环境的影响等不同目标要求,选择了在工艺、安全、造价等方面都比较满意的支护方案,并通过实际案例对该方法进行了说明.实践表明:该方法能够为类似工程的决策者提供参考依据,具有一定的理论意义和实际应用价值.

In order to select a satisfying scheme, by using the theory of fuzzy mathematics as well as multiple objectives decision making, this paper gives a supporting program which considered different target requirements,such as construction technology, economy, construction period and influence on the surroundings. At last, a practical example illustrates the validity of the method provided in this paper. Practice shows that this method can provide reference basis of similar projects for decision makers, which has a certain theoretical significance and practical application value.
