托板桩复合地基桩体荷载分担比研究

A research about load share ratio on the compound foundation pile of the supporting plate pile

采用有限元法研究了托板桩复合地基垫层内摩擦角、弹性模量、垫层厚度以及桩间距、桩体持力层对桩体荷载分担比和地基沉降的影响。研究结果表明,在满足地基沉降和承载力的前提下,应采用合理的垫层厚度、弹性模量和桩间距以减少工程费用。

The paper adopts the finite element method research about the influence of the friction angle in pad, elasticity modulus, cushion thickness, the piles spacing and pile supporting course to the pile load share ratio and the foundation settlement, on the compound foundation pile of the supporting plate pile. The research results showed ： on the precondition of satisfying the foundation settlement and load capacity, it adopts the rational cushion thickness, the elasticity modulus and the piles spacing to reduce the engineering cost.
