Numerical Analysis of Soft Soil Ground Consolidation Settlement

Abstract:

An artificial island under construction is located at an open sea and constructed by such a way that island walls are composed of steel cofferdams inserted into impermeable layers and then filled with sands. Grounds on the island are covered by thick soft soil layers with high water content, large compressibility and low bearing capacity, and treated by a jointed dewatering surcharge preloading method. In order to know the settlement property of the soft soil ground, the numerical analysis is implemented. During the analyzing, the parameters are adjusted and calculated through inverse analysis compared with practical measured data. So the numerical calculation results are more reliable. The analysis results indicate that the residual settlement of the soft soil ground is 9cm, and main ground consolidation settlement will be completed for two years after construction finished.
