摘要

基于弹性薄板理论，用半解析方法分析了考虑地下室侧墙平面外的弯曲以及纵向平面内整体弯曲情况下筏板基础、上部结构与地基的共同作用，与不考虑侧墙影响的计算结果以及实测结果比较表明，考虑地下室侧墙平面外的弯曲以及纵向平面内整体弯曲的结果与实际较接近。在此基础上，分析了侧墙刚度对底板受力的影响，以及底板尺寸变化时侧板刚度对底板受力的影响。

Abstract

Based on the theory of elastic thin plate

semi-analytic method is applied to study the interaction among raft

up-structure and ground by considering the horizontal outer flexure and longitudinal plane total bend of underground construction sidewall. Comparing with the computational and field measured results without taking the effect of the sidewall

shows it is more practical for considering the horizontal outer flexure and longitudinal plane total bend. Based on the above study

the effect of sidewall stiffness on the forces acted on raft is analyzed; and the situation by changing the raft size is also discussed.
