摘要
在用真空预压法进行软基处理过程中,对于真空预压引起的竖向、水平向影响范围的大小往往决定着软基处理的成败。为此,以江门新会南车轨道交通车辆修造基地大面积软基处理工程为依托,通过在加载区内进行表面沉降、各深度真空度和孔隙水压力的监测,在区外进行表面沉降、水平位移等数据观测的方法对整个真空加载过程进行定期数据采集,在前人研究成果的基础上分析得到真空预压法加固大面积软基工程中真空荷载影响范围,可在处理效果和对周边影响方面为珠三角地区类似工程的施工和设计提供可靠数据和技术参考。
In the soft ground treatment by vacuum preloading,the horizontal and vertical influence scope caused by the vacuum preloading is essential to the soft ground treatment project.Based on the CSR rail vehicle maintenance-built base＇s large area soft ground treatment project,according to the monitoring data of surface settlement,vacuum degree and pore water pressure of different depths in the loading area,as well as the surface settlement and horizontal displacement outside the loading area,we get the influence scope of soft ground treatment by vacuum preloading which can provide reliable data and serve as reference for the design and construction of similar projects in the Pearl river delta region.
