ANALYSIS OF VACUUM-PRELOADING-DYNAMIC COMPACTION METHOD AND TREATMENT EFFECT FOR SOFT SOIL OF FUJIAN ZONE

Based on foundation treatment engineering for saturation soft soil of Fujian zone, Vacuum-Preloading-Dynamic Compaction Method was put forward. It fulfiled require of settlement and bearing capacity, Through foundation settlement observation, change of water content, void ratio, compression modulus, Ps value and shear vane test strength of silt soil in treatment fore and aft, farther sum-up relationship between water content and modify coefficient of settlement, practice proved remarkable reference value of engineering practice.
