摘要
基坑支护方案综合评价可以为方案比选提供一定的决策依据。尝试运用集对分析和TOPSIS耦合建立改进的TOPSIS模型,按照实用性、代表性等原则建立基坑支护方案综合评价指标体系。各指标的权重采用组合赋权法,考虑各指标的主观赋权和客观赋权,同时兼顾专家的实践经验和原始数据蕴藏的客观属性。实例应用结果表明,该模型用于基坑支护方案的综合评价是可行的,评价结果较为可靠、合理。
Comprehensive evaluation provides a basis for the selection of foundation pit support schemes. Set Pair Analysis coupled with TOPSIS （ Technique for Order of Preference by Similarity to Ideal Solution） is used to build an improved SPA-TOPSIS model. Practicality and representativeness are chosen as principles of the evaluation index set. Combination weighting method is adopted to take the subjective and objective weight of each index into account, and meanwhile the expert＇ s practice experience and the objective attribute of original data are also considered. The application result shows that the method is feasible, the evaluation result is reliable and reasonable.
