Numerical analysis of pile-anchor supporting structure in deep excavation
摘要
Abstract
The simulation software of FLAC3D was applied to calculate and analyze the actual pile-anchor supporting structure of the deep foundation pit in Shenyang.This research mainly focused on the pile top displacement of piles,horizontal displacent of pile and internal forces in the excavation process.Furthermore,field-measured values and the calculation results by simulation software were compared and analyzed.And on this basis,change the dip angle of anchor and embedded depth of the supporting design and explore these factors on the influence of pit deformation.The results prove that the simulation value and the measured value is basically the same,and the numerical simulation result is reliable.The maximum value of horizontal displacement and bending moment of pile appear in the position of the pile body about 8m rather than the top in the range of the supporting pile;design of the embedded depth of the pile desirable 4～6 m,and the dip angle of anchor is appropriate when it ranges from 5°～30°.关键词
