| 摘 要： | 分析介绍了一种新型的真空预压处理技术-增压式真空预压应用于广珠铁路珠海西站软基处理。为验证增压式真空预压的适宜性，在现场设置四个不同设计方案的试验断面，分别进行了表层沉降、分层沉降和孔隙水压力的对比分析。试验结果表明，采用增压式真空预压提高了预压期的沉降量，缩短了固结时间。

| Abstract: | This paper introduced a new type vacuum preloading technology—air-boosted vacuum preloading applied in Zhuhai West Station Soft Foundation in Guangzhou-Zhuhai Railway.In order to verify the applicability of air-boosted vacuum preloading,four different designed sections are set on site to separately analyze surface settlement,layered settlement and pore water pressure.The test results showed that air-boosted vacuum preloading improved settlement in preloading period and shortened consolidation time. |
