粤电中山项目真空预压监测成果分析

粤电中山项目软基采用真空预压法处理,为达到监控施工安全和验证地基处理效果的目的,进行了施工监测。施工过程中采用了膜下真空度、地面沉降、分层沉降、地下水位、孔隙水压力、深层水平位移等多种监测方法,根据监测的数据推算了最终沉降,计算了固结度,为卸载提供了依据,获得的实践经验可在其他类似工程中推广应用。

Analysis of Monitoring Results of Vacuum Preloading on Zhongshan Yuedian Project

Vacuum preloading method was adopted in soft clay treatment of the design for Zhongshan Yuedian Project.To monitor the construction safety and verify the effect of foundation treatment,the construction monitoring was undertaken. Some monitoring methods were adopted in course of vacuum preloading,such as vacuum degree under membrane,ground settlement,layered settlement,groundwater level,pore water pressure and deep horizontal displacement.The final settle-ment and consolidation degree are also calculated according to the monitoring data.Evidences for unloading are provided and practical experiences gained can be applied in other similar projects.
