Research on reinforcement effect of vacuum preloading to treatment of the soft foundation

[摘要] vacuum preloading method is a commonly used method to reinforce soft ground at present. Monitoring during construction stage is a dynamic monitoring, which is a standard to judge the quality of construction. This paper relies on the reclamation project of Tianjin Port Industrial Zone in North China, analyzed the monitoring purposes, monitoring method and collection data. Results had shown that vacuum preloading monitoring can make an accurate evaluation of construction quality during construction. The project practice can provide reference for similar projects.
