微型桩水平承载特性的现场试验与数值模拟分析

Field Test and Numerical Simulation Analysis of Micro Pile Horizontal Load Bearing Characteristics

水平承载微型桩在工程现场的静载试验,对比了不同桩长、不同抗弯刚度微型桩的水平承载特性,在实验研究基础上,对桩径、桩身模量等主要因素对微型桩水平承载特性影响进行的数值分析,得出结论:通过合理选择微型桩桩长、桩径以及桩身插设钢管等,可以提高水平承载微型桩的承载能力。

Static loading test on the part of micro pile of horizontal load bearing at the construction site com- pares horizontal load bearing characteristics of micro piles of different length and bending rigidity. A numerical simulation analysis has been made of the influence of the principal factors such as pile diameter, pile modulus, etc, on micro pile horizontal load bearing characteristics, which can lead to a conclusion that micro pile horizon- tal load bearing capacity can be improved through appropriate choice of pile length, pile diameter and properly inserting piles in the steel pipes.
