基于模糊综合评价法的地基处理与优化选择

Fuzzy Comprehensive Evaluation Assessment on Based Selection and Optimization of Foundation Treatment

针对当前地基处理方案优化选择仍存在许多不确定性与模糊性的特点,提出模糊综合评价方法以解决优化选择评价指标难以量化问题.通过对地基处理方案择优指标比较识别,主要从安全可行性、施工便捷性、工程造价、环境效应4个方面构建择优评价指标体系,包括12个二级评价指标,兼顾主客观因素,其中采用层次分析法确定各评价指标相对权重并结合专家评分,目的是能客观确定出最优地基处理方案.

There are still many uncertainties and fuzziness for optimization and selection of current foundation treatment,a fuzzy comprehensive evaluation method B proposed to solve the optimization problem which is difficult to quantify of selection and evaluation. Through comparison and recognition to the merit index of foundation treatment plan,the main merit evaluation system constructed from four aspects of security feasibility,construction convenience,cost and environmental effects,it includes 12 secondary evaluation,both subjective and objective factors are taken into the system,in which hierarchical analysis and expert ratings is used to determine the relative weight of each index,the purpose is to objectively determine the optimal method of foundation treatment.
