摘　　要：介绍真空堆载联合预压软基处理工程中常用的监测手段及监测方法。结合工程实例,综合运用表层沉降监测、孔隙水压力监测、分层沉降监测、地下水位观测等手段,控制施工加载期的加载速率和荷载维持时间,确保施工期的安全性,并通过量测数据进行固结度计算和工后沉降的估算,以期达到信息化施工的目的,可供软土地基处理设计与施工参考。Common means and methods for monitoring and measurement in improvement of soft soils with the vacuum surcharge preloading technique are introduced. The results of improvement of soft soils with the vacuum preloading technique are analyzed by jointly using the means and methods of surface settlement monitoring and measurement, measurement of pore water pressure, monitoring and measurement of layer settlement and observation of ground water in the light of engineering cases, which may serve as reference for the design and implementation of soft soil improvement projects.
