[提要] 采用有限元計算方法,應(yīng)用正交試驗原理,對水泥土攪拌樁擋墻進(jìn)行優(yōu)化設(shè)計,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,對減小沉降有利而且經(jīng)濟合理。
[關(guān)鍵詞] 正交試驗 基坑 優(yōu)化設(shè)計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
