摘　　要：介绍了嘉兴晶辉广场深基坑工程的设计方案,并对施工过程进行监测,做到了信息化施工。通过对施工过程中深层土体位移变化、周边道路的沉降变形、锚桩拉力变化以及坑外地下水位变化进行分析,结果表明在软土地区预应力锚桩的预应力衰变速率较大,钢支撑对土体位移的限制作用较好,SMW工法桩有很好的止水效果。The design scheme of deep foundation excavation engineering of Jiaxing Jinghui square and the monitoring of the construction process are introduced, which makes the information construction. Authors discuss the variation of deep soil displacement, the variation of road settlements, the variation of tension force of anchor pile and the variation of groundwater level outside the excavation in detail. The result shows that the prestress of anchor pile decay faster in the soft soil area, the steel braced has a good supporting effect on the soil displacement, and SMW pile can effectively seal water.
