Analysis of Deformation and Reinforcement Measures for Rigid Pile Composite Foundation In-inhomogeneous Strata
Rigid pile composite foundations are gradually being widely used due to the advantages of small post-work settlement,short construction period,strong overall stability and high socio-economic benefits.It is also accompanied by a number of engineering problems with rigid pile composite foundations under inhomogeneous strata being prone to stability problems.A typical case of rigid pile composite foundation in inhomogeneous strata is studied,and a three-dimensional model is established using finite element software to reveal the deformation law of rigid pile composite foundation in inhomogeneous strata before and after the improvement scheme.In addition,the enhancement effect of three reinforcement methods on the stability of rigid pile composite foundations is also investigated.The results show that the rigid pile composite foundation in inhomogeneous strata will produce partial stress and cause uneven settlement,and the structural stability is poor.The improvement scheme can effectively reduce the embankment settlement and improve the overall stability of the structure.The crossbeam reinforcement can effectively improve the horizontal stability of the rigid pile composite foundation.
