基于MIDAS深基坑桩锚支护数值模拟分析
Numerical Simulation Analysis of Pile-anchor Retaining in Deep Foundation Based on MIDAS
摘要
Abstract
Based on foundation trench of a survey and design institute,the numerical simulation analysis on model of triaxiality deep foundation established by using large finite element software（i.e.MIDAS） was carried out.The engineering condition and model correlation are introduced.The deformation value of city structure and the observe value are compared.The viability of model is verified.Moreover,it is described that on the basement excavation and construction process,the maximum horizontal displacement of the pile at the top,the midpoint of the edge of the pit,especially near the midpoint of the long side;the vertical edge of the maximum settlement of excavation of soil occurred in a certain distance behind the pit and the anchoring strength is distributed evenly in the free section and decreased gradually variation,and it provides some references for deformation control design and engineering monitoring.关键词
