摘要
Abstract
Taking the h-type double-row pile support structure of a deep foundation pit project in Shenzhen as the research object,a numerical analysis model of h-type double-row piles was constructed using MIDAS-GTS finite element software.Based on the verification of the model's effectiveness,the influence of different cantilever lengths(0 m,2 m,4 m,6 m)of the rear-row piles on the deep horizontal displacement,bending moment,and shear force of the h-type double-row pile support structure were explored.The research results indicate that,under the same excavation depth and design parameters of the foundation pit,h-type double-row piles can reduce the horizontal displacement of the support structure and optimize the distribution of bending moment and shear force of the front-row piles compared to traditional gantry double row piles.Based on a comprehensive analysis of the deep horizontal displacement,bending moment,and shear force of piles under different cantilever length conditions,it is reasonable to take a cantilever length of 6m for the rear-row piles in this engineering case.关键词
