Analysis And Research On Soft Soil Foundation Circular Coal Yard Pile Soil Interaction

In recent years,the environmental quality in China has gradually become the major problem plaguing people's lives,in order to reduce the environmental pollution,coal yard design in China with large enclosed circular coal yard as the optimal choice.Unlike the conventional building pile foundation,circular coal yard is built on soft soil foundation,pile foundation should bear the horizontal force caused by horizontal displacement caused by pile soil pile week load of the coal under the vertical load at the same time.Based on the analysis of the related research at home and abroad,this paper makes use of ANSYS finite element software to analyze the pile-soil interaction:(1)Based on the soil parameters of the geological survey report,the single pile test is simulated by using the finite element software.By adjusting the compression modulus,Poisson's ratio and cohesion of the soil,it is concluded that the compression modulus of soil has the most important influence on the stress and deformation of the pile foundation.By adjusting the parameters of soil,the finite element simulation results and actual test of single pile are consistent,so as to verify the accuracy of finite element model,and provide more accurate soil parameters for finite element analysis of the pile foundation.(2)By comparing the three row piles and four piles of two kinds of pile arrangement,and on the basis of comparing with the coal pile load in two cases,the four row pile layout is reasonable,which means that in the coal pile load,research the necessity of pile horizontal load pile soil.(3)To establish a three-dimensional finite element model using ANSYS finite element model,by adjusting the parameters of soil stress and deformation influence on the pile compression modulus of soil layers,and find out the regularity,formulate the corresponding reinforcement measures,provide a reference for the future engineering application.
