PVD-Aided Consolidation with Spatial Variations in Soil Properties and Initial Excess Pore Pressure
Analytical solutions for determining the degree of consolidation of clayey soils caused by the installation of prefabricated vertical drains (PVDs) are developed by considering the variations of initial excess pore pressure and soil properties with depth. The PVD is assumed to be installed in a clayey deposit with multiple layers, and the effect of soil disturbance caused by PVD installation is considered in the analysis. The analytical solutions are developed with the assumptions of equal-strain consolidation and continuity of flow that follow Darcy’s law. These closed-form solutions are applicable for different cases that are expected to commonly occur in real field problems. It is observed based on parametric studies that different spatial variations of coefficient of consolidation and initial excess pore pressure impact the rate of consolidation differently. A numerical example is presented that demonstrates the use of the developed solutions.
