摘　　要：对西安大夏国际中心深基坑支护方案评价指标进行优选,以钻孔灌注桩、复合土钉支护、地下连续墙3种技术方案为评价对象,采用专家咨询、查阅文献、理论分析相结合的评价方法,从支护效果、稳定安全系数、施工可行性等9个指标初步构建深基坑支护方案评价指标体系.运用专家打分和层次分析相结合的方法对初步选择的评价指标进行定量分析,计算各个指标的权重,并进行定性分析,对初选指标进行分析、筛选、优化.最终舍弃了稳定安全系数和施工连续性指标,得到最终优化的评价指标体系.The three schemes （bored piles, composite soil-nail supports and underground continuous walls） were chosen as evaluated objects,and the combination method of expert advice,literature reference and theoretical analysis was adopted to set up the evaluation index system of deep foundation pit support schemes based on the nine indices such as support effects, stable safety, construction cost, construction fea- sibility, effects on the environment, security, duration, etc. And the experts marking method was combined with the analytic hierarchy process to analyze and filter the primary indices. Finally, the optimal evaluation index system was obtained which excluded the stability-security factor and construction continuity.
