[提要] 采用有限元計(jì)算方法，應(yīng)用正交試驗(yàn)原理，對(duì)水泥土攪拌樁擋墻進(jìn)行優(yōu)化設(shè)計(jì)，分析了擋墻深度L、寬度B和墻前坑底加固區(qū)寬度C各因素對(duì)基坑變形的影響。分析表明，擋墻深度、寬度和墻前坑底加固區(qū)寬度存在一優(yōu)化組合，對(duì)減小沉降有利而且經(jīng)濟(jì)合理。
[關(guān)鍵詞] 正交試驗(yàn) 基坑 優(yōu)化設(shè)計(jì)The influence on the retaining wall,which was exerted by the depth and width of the retaining wall and the width of reforced soil adjacent to the wall at the bottom of the pit, is analysed. The orthogonal method and 3DF were used in order to discuss the optimum combination. The author hoped that the result could be referred to the similar projects.
Keywords: orthogonal method; foundation-pit; optimum design
