A Consolidation Solution of Soft Soil Deposits Improved with Prefabricated Vertical Drains and Deep Cement Mixing Columns
Recently, a new technique method has been developed in ground improvement field, namely the combined method. This method involving the utilization of both prefabricated vertical drains (PVDs) and deep cement mixing (DCM) columns was applied to improve shear strength and accelerate consolidation rate. The goal of this study is to propose a simple analytical solution for consolidation of soft soil improved by PVDs-DCM columns, in which effects of smear zone due to drains installation and nonlinear behavior of permeability and compressibility during consolidation process are considered. Subsequently, the proposed method was applied to a test embankment in China, which used the combined method for ground stabilization. The axisymmetric model of composite ground in finite element method (FEM) is also implemented to analyze the consolidation behavior of soft soil improved by the combined method under test embankment. The proposed solution provided a good result with the monitoring data and FEM results.
