A Semi-Analytical Method to Calculate the Consolidation Problem of the Soilbag Filled with Mud Soil Buried with PVD

Abstract:

A semi-analytical method to calculate the degree of consolidation of the soilbag filled with mud soil with PVD built in is proposed. First a unit-body model is founded to obtain the low-dimensional solution. Through the successive iterations of the low-dimension solution, the solution considering the situation when the physical or geometry parameters of the model vary is finally obtained. The solution of the rectangular area is obtained by summing solutions of two square area with coefficients set. A lab experiment was done in Liubao test base of Zhejiang institute of hydraulics and estuary to research the consolidation performance of soilbag filled with mud soil buried with PVD. The semi-analytical method and FEM are applied to calculate the lab experiment case. From the comparison among the lab experiment, the semi-analytical method and FEM, it shows that the semi-analytical method calculates a good result of the degree of consolidation of the lab experiment.
