Research on Pore Pressure and Groundwater Level in Vacuum Drainage Preloading

In terms of the deficiency of vacuum preloading theory research,data based on the field test is employed and relation curves of pore water pressure and groundwater level with time are established,seepage field theory is adopted to analyze vacuum preloading reinforcement mechanism,changing law of pore water pressure and groundwater level,as well as the relationship between both,and some useful conclusions are obtained.
