Pore Water Pressure Variation Characteristics Analysis of Soft Soil Foundation Disposed by Dynamic Drainage Consolidation Method

Abstract:

The pore water pressure variation during the process of dynamic drainage consolidation is calculated and analyzed with numerical simulation method, using constitutive model of Finn. The pore water pressure in mud presents transient vibration process, and decreases with depth. The pressure in mud is always higher than in sang bag well, which reveals that sang bag well is an effective vertical drainage channel in process of dynamic drainage consolidation. In addition, seen from the characteristics of pore water pressure variation, effective consolidation depth can be accurately forecasted.
