某集装箱码头真空联合堆载预压软基处理研究

Base on the special geological condition and soft soil characteristics in a Container Terminal, analyzed the measured date of surface settlement, pore water pressure, deep horizontal displacement from reinforcement area of Vacuum-surcharge Preloading ;compared with the date of pore water pressure measured of Previous works and analyze the reasons of pore water pressure in different; studied the permeability of the impact of degree of consolidation, identify the relationship between the consolidation coefficient and pressure and conducted a preliminary study of this relations. Measured data show that Vacuum-surcharge Preloading is an effective method of foundation strengthening. This project generated a large amount of settlement (part of more than 1000mm), while the latter deformation> 1mm / d, show that the rheological properties of soil in the project performance is more prominent, and necessary for long-term settlement of the latter measurements.
