地基基础部分1、在进行软弱下卧层承载力验算时,对于偏心荷载可采用平均基底压力求解下卧层顶面的压力。2、注意不同验算条件下荷载组合不同(验算地基承载时和基础裂缝宽度,采用正常使用标准组合,验算地基变形,采用准永久组合(恒荷载+可变荷载,准永久系数),不考虑风荷载和地震荷载;验算结构配筋,采用基本组合,验算挡土墙稳定,采用基本组合,荷载效应系数为1.0)。
Foundation part 1, in the calculation of the bearing capacity of the weak underburden, the average base pressure for the eccentric load can be used to solve the pressure on the top surface of the subsoil. 2. Pay attention to different load combinations under different checking conditions (check the foundation bearing and foundation crack width, use normal combination standard, check foundation deformation, use quasi-permanent combination (constant load + variable load and quasi-permanent coefficient), without considering wind Load and seismic load; check the structural reinforcement, using the basic combination, verify the retaining wall stability, using the basic combination, the load effect coefficient of 1.0).
