[提要] 深基坑支護(hù)系統(tǒng)方案的優(yōu)化設(shè)計(jì)是一個(gè)相當(dāng)復(fù)雜的系統(tǒng)工程優(yōu)化問題。根據(jù)長江一級階地的工程地質(zhì)和水文地質(zhì)特點(diǎn)構(gòu)造層次結(jié)構(gòu)模型，采用層次分析方法建立起深基坑支護(hù)系統(tǒng)方案的評價(jià)體系。通過對各種可行方案的定量評價(jià)對比，優(yōu)選出最佳方案以達(dá)到深基坑支護(hù)系統(tǒng)方案優(yōu)化設(shè)計(jì)的目的。并對評價(jià)指標(biāo)進(jìn)行了規(guī)一化處理。
[關(guān)鍵詞] 基坑支護(hù) 方案 優(yōu)化 指標(biāo) 權(quán)重 規(guī)一化It is very difficult to optimize the bracing project of deep foundation pit. By the analytical hierarchy pro-
cess method, the project evaluation system is set up in accordance with engineering geological and hydrological geological condition of the first Yangtze River's terrace. The optimal plan is elected by appraising all possible projects qualitatively. The qualitative and quantitative evaluation targets are dealt with by the normalized method.
Keywords: bracing; foundation pit; project; optimization; target; relative weight number; normalization
