摘　　要：采用有限元计算方法 ,应用正交试验原理 ,对水泥土搅拌桩挡墙进行优化设计 ,分析了挡墙深度L、宽度B和墙前坑底加固区宽度C各因素对基坑变形的影响。分析表明 ,挡墙深度、宽度和墙前坑底加固区宽度存在一优化组合 ,对减小沉降有利而且经济合理。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.
