真空预压在大面积场地形成中的加固效果分析

摘要

介绍了上海迪士尼场地形成工程中采用的真空预压地基处理方法，并结合实测数据分别从地表沉降、孔隙水压力、分层沉降等方面，对真空预压地基处理加固效果进行系统分析，在此基础上，得出了一些有意义的结论，为类似大面积场地形成工程提供借鉴和参考，更好的指导真空预压地基处理设计工作。%The paper introduces the foundation treatment method of vacuum preloading for site formation of Shanghai Disney land. According to the practical project datum,the effect of vacuum preloading foundation treatment is systemically analyzed from the results of ground settlement, pore water pressure,layered settlement. On the basis of this,some meaningful conclusions are drawn,which can provide references for other similar projects and can better guide the design of vacuum preloading foundation treatment.
