（中國地震局地震研究所，武漢430071）[摘要] 提出了較系統(tǒng)的深基坑支護方案優(yōu)選模式：利用層次分析法對各影響因素的權(quán)重值進行了求解，運用模糊綜合評判方法對初選出的支護方案進行優(yōu)選。結(jié)合具體工程實例，采用了系統(tǒng)工程中的層次分析法、多目標(biāo)模糊決策理論等方法對該工程支護方案進行優(yōu)化選型，不僅可以方便快捷地確定權(quán)重值，還可以降低層次分析法中人的主觀性影響，使優(yōu)選方法科學(xué)易行，較好地滿足了實踐要求。

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.
