摘要
Abstract
During the process of vacuum preloading reinforcement of saturated soft clay,the dissipation value of pore water pressure has always been regarded as an important index of reinforcement effect.Due to its complicated dissipation law and unclear mechanism,the dredger-filled reinforcement projects in Leqing Bay and Bangladesh were selected to study the influence of soil layer properties on the dissipation of pore water pressure,the correlation between groundwater level and pore water pressure as well as the correlation between the vacuum degree under membrane and pore water pressure based on the field monitoring data on pore water pressure,vacuum degree,groundwater level,and surface settlement.Furthermore,the dissipation law of pore water pressure in saturated soft clay was initially grasped,which had certain guiding significance for revealing the vacuum preloading mechanism and improving the design and construction of vacuum preloading.关键词
