Soft Soil Foundation Treatment of Coal Yard Based on Numerical Simulation Analysis
The treatment of soft soil foundation in the southeast coastal area is crucial for various construction projects.To control post construction settlement and ensure the stability and safety of large-scale coastal yard foundations,research on settlement deformation and numerical simulation during yard foundation treatment and post production loading process is carried out.Taking the foundation treatment project of a coal-fired power plant in Zhoushan as an example,the settlement of natural foundation and foundation treatment based on plastic drainage plate preloading method was calculated,and the stability of the foundation under pile load was analyzed using the finite element software PLAXIS 2D.The research results indicate that if natural foundations are used in coal yards under the action of coal stacking,the post construction settlement is large and the consolidation settlement time is long.Therefore,foundation treatment should be carried out as soon as possible.The method of vacuum build-up charge combination preloading for foundation treatment is adopted in coal yard,which can effectively improve the problem of foundation settlement.
