摘　　要：为解决软土地区基坑施工存在水平位移量大,影响施工质量的问题,开展软土地区基坑分区开挖相邻深基坑相互影响规律研究。首先,构建相邻基坑数值模拟模型。其次,分析共用地连墙基坑开挖相互影响性状。最后,分析基坑间增加挡土结构对减少相邻基坑相互影响规律。结合得到的分析结果对软土地区基坑中的支护结构进行优化,以此确保基坑不会发生较大水平位移,促进施工质量提升。In order to solve the problem of large horizontal displacement in the construction of foundation pits in soft soil areas,which affects the construction quality,a study was conducted on the mutual influence law between adjacent deep foundation pits in soft soil areas foundation pits partition excavation.Firstly,the numerical simulation model for adjacent foundation pits was constructed.Secondly,the mutual influence characteristics of the excavation of the shared ground connecting wall foundation pit was analyzed.Finally,the effect of adding retaining structures between foundation pits on reducing the interaction between adjacent foundation pits was analyzed.Combined with the obtained analysis results,the support structure of the foundation pit in soft soil areas was optimized to ensure that the foundation pit will not experience significant horizontal displacement and promote the improvement of construction quality.
