[摘要]  提出了较系统的深基坑支护方案优选模式：利用层次分析法对各影响因素的权重值进行了求解，运用模糊综合评判方法对初选出的支护方案进行优选。结合具体工程实例，采用了系统工程中的层次分析法、多目标模糊决策理论等方法对该工程支护方案进行优化选型，不仅可以方便快捷地确定权重值，还可以降低层次分析法中人的主观性影响，使优选方法科学易行，较好地满足了实践要求。

Abstract: A systematical selected patterns is suggested. The result of multiplicity of weight of each affect factor by Analytical Hierarchy Process (AHP) is found and the first-selected supporting scheme is optimized by fuzzy comprehensive evaluation. Combining practical project to optimize supporting scheme by AHP, multi-target decision theory, etc., not only the weight can be determined conveniently, but the influence of human's subjectivity in AHP can be lowered. By doing this, the method of optimal selection will become more effective and practical.
