真空预压试验在上海迪斯尼工程场地形成中的应用及测试分析

Application and analysis of vacuum preloading tests on engineering site formation of Shanghai Disneyland Park

系统介绍了上海迪斯尼工程场地形成过程中的真空预压试验,对由于真空预压而引起的沉降变形、分层沉降、孔隙水压力等试验结果进行了系统分析。分析结果表明:在上海等软土地区,进行真空预压对大面积地基进行处理,可以取得良好效果,试验结果满足工程要求。

Vacuum preloading tests on engineering site's formation of Shanghai Disneyland Park are systematically introduced. The test results of deformation, layered settlement and pore water pressure are summarized and analyzed. The results show that the vacuum preloading tests can achieve a good effect on large-area foundation treatment in Shanghai soft soil area, and the test result can satisfy engineering requirements.
