Three-dimensional numerical simulation of foundation settlement of storage tank group in soft soil area
2009
In the process of constructing storage tank in soft soil area,the differential settlement is one of the main controlling factors.As the result of the influence of some dynamic factors such as tank spacing,pore water pressure change,the issue of the settlement tends to complex.By using FLAC3D numerical simulation software,a three-dimensional nonlinear finite difference model was established.Synthesizing various factors,the deformation behavior and the stress distribution of the foundation of storage tank group with different clear distance in soft soil area were studied.The effects of different clear distances on the tank settlement and differential settlement were analyzed.The results show that in considering the additional stress of foundation soil and the excess pore water pressure together,it is reasonable when the tank spacing is 0.6 times the tank diameter.
