模糊综合评判在基坑截水帷幕方案选择中的应用

Application of Fuzzy Comprehensive Evaluation in Choosing the Plan of Foundation Pit in Curtain for Cutting off Water

不同的基坑支护方案的施工成本、工期以及对周围环境的影响可能完全不同,因此多方案的优化选择是我们经常需要面对的问题。采用模糊综合评判能有效克服不确定性因素的模糊性对不同方案对比的影响,把不同方案的各种定性指标定量化处理,使方案优化选择更加科学有效。本文在成功应用于银河星辰花园基坑截水帷幕方案优化选择的基础上,对不同模糊运算模型进行了对比,对定性指标定量化处理提出了相应的解决办法。

Since the cost, construction period and influence on surrounding environment of different support plans of foundation pit may be totally different, the optimization of different plans is the problem we have to face. The application of fuzzy comprehensive evaluation can efficiently overcome the influence of the fuzzy of uncertain factors on the contrast of different project and quantify the quality indices to make the plan choice more effective and scientific. Based on the successfully choosing the plan in the residential quarter of Yinghe Xincheng Garden by fuzzy comprehensive evaluation, different fuzzy calculation models were compared and the solution was provided to quantify the quality indices as well.
