STUDY ON THE EFFECT OF PORE WATER-PRESSURE IN TECHNOLOGY OF DEWATERING SOFT SOIL FOUNDATION TREATMENT

Dewatering is a new technology in soft soil foundation treatment. By dewatering, hydrostatic pressure decreases and effective normal stress correspondingly increases. Then the soft soil is consolidated and subded . In this paper, by analyzing pore-water pressure monitoring data of the dewatering and preloading test on a project in Pudong , the mechanism and pore water effect of dewatering foundation reinforcement are briefly discussed.
