Numerical Analysis of Coupled Fluid -- Mechanical and Drainage Consolidation of Soft Soil

Based on solid-fluid interaction theory, a 3D model of the drainage wells with depth 10m, width 15m and radius 25m is established. The model is then used to carry out the performance analysis of drainage consolidation of saturated soft soil. Using this model of FLAC3D numerical solution and analytic...

Summary:Based on solid-fluid interaction theory, a 3D model of the drainage wells with depth 10m, width 15m and radius 25m is established. The model is then used to carry out the performance analysis of drainage consolidation of saturated soft soil. Using this model of FLAC3D numerical solution and analytic solution, the dissipation of pore water pressure and maximum amount of vertical settlement of soft soil are calculated. The coupling time in this calculation is 30s. Meanwhile, the results when coupling times are 5s, 10s, and 20s are also recorded. Through compare and contrast, we find that the degree of pore water pressure dissipation decreases as the radius of model increases and as the coupling time increases.
