【正文】 ngineering geologic conditions and hydrogeological conditions, also precedents in the requirement of deformation and stability,connecting with the ingredient economy and feasibility, the author chosen a pound retaining methods of Pile and Anchor. According to Foundation plicated surrounding environment, difference of soil and the feasibility of construction designated segments of six calculated to experiment of local analogous engineering and account method providing by various rules while designing and accounting , each design coefficient was content with the requirement of stability and deformation. According to foundation engineering hydrogeology conditions, determine the sand and gravel layer waterproof curtain, consider economic and the effect of sealing under the two conditions to determine the foundation application of high pressure spraying waterproof curtain to the requirement of erector, the author established a detail and scientific construction anization total construction cost of the project budget is yuan ,the unit construction cost of the project budget is yuan per square meter.Key words: foundation pit 。根據(jù)基坑復(fù)雜的周邊環(huán)境、土層差異和施工可行性將基坑劃為六個(gè)計(jì)算段，設(shè)計(jì)計(jì)算參考了當(dāng)?shù)赝?lèi)工程的經(jīng)驗(yàn)和各種規(guī)程規(guī)范提供的計(jì)算方法，各設(shè)計(jì)參數(shù)滿(mǎn)足穩(wěn)定和變形的要求。中南大學(xué) 2022
