摘　　要：在建立深基坑支护设计的评价指标体系的基础上,首次采用基于专家评分法和均方差权值决策法的复合模型进行深基坑支护方案的选取,并应用实例加以论证。结果表明,基于主客观评价方法相结合的复合模型的深基坑支护方案优选结果更加真实可靠。Based on the system of appraisal index of deep foundation bracing desig.n, at the first time, the complex method of expert point rating and mean-square deviation weight decision was used to choose the optimum desigh of deep foundation bracing. The result showed that the feasibility and validity of the complex model based on the two method is illustrated and verified by a case study.
