Numerical Analysis of Equivalent Stiffness Parameters of Prestressed Pipe Pile Soil Composite Foundation
In order to study the influence of prestressed pipe piles on the stiffness parameters of muddy soft soil foundation,this paper relies on the Zhejiang Liansu Phase Ⅱ project,and uses ABAQUS finite element soft modeling and C++programming to numerically simulate and analyze the stiffness parameters of composite foundation formed by prestressed pipe piles in muddy soft soil.The research results show that:①Muddy pile soil composite foundation can effectively increase the elastic modulus of composite foundation,But non-linear growth;② The Poisson's ratio of silt pile soil composite foundation is inversely proportional to the size of the pile diameter.When the pile length exceeds the silt layer,increasing the pile length has no significant effect on the Poisson's ratio of the composite foundation.However,when it exceeds the silt layer,the calculation results converge.The above calculation results are applicable to coastal city reclamation areas and accumulate engineering experience for other coastal cities.
