| 摘 要： | 对于深基坑支护系统方案评价提出一种新的方法,以避免主观判断的不确定性和随意性。针对传统信息系统项目评标中单纯由主观判断确定指标权重方法的不足，提出了将主观判断与客观情况相结合、定性、定量相结合的熵权法来确定指标的权重系数，进而将逼近理想解法与熵权法综合集成进行合理方案的评价。将该方法应用于深基坑支护系统方案过程评价的实践，取得了较为满意的结果。

| Abstract: | A new method is put forward to evaluate projects of bracing system for deep excavation to avert uncertainty and random caused by subjective estimation. Weight coefficients of indices are determined by entropy weight method, which combines subjective estimation with objective facts, combines qualitative analysis with quantitative analysis. At the same time, TOPSIS method is associated with entropy weight method to make a rational evaluation. This method has been applied to real project of bracing system for deep excavation; and the result is approvable. |
