摘　　要：城市软土路基修建支挡结构,不仅需要进行软土路基处理,而且需要考虑市政管线穿越,减少开挖量等问题。传统支挡结构无法满足设计要求。论文结合工程实际,设计出一种新型桩承式挡墙结构,对结构的尺寸进行多次调整并验算,最终设计出一种既安全又经济的设计方案。In the construction of retaining structure for urban soft soil subgrade, not only soft soil subgrade treatment is needed, but also municipal pipeline crossing and excavation reduction are considered. The traditional retaining structure can not meet the design requirements.In this paper, a new type of pile supported retaining wall structure is designed based on the engineering practice. The size of the structure is adjusted and checked many times, and finally a safe and economic design scheme is designed.
