摘要
地下空间工程因抗浮不足引发的地下结构开裂、破坏是近年来较为普遍的工程热点、难点问题。本文针对四川某建筑地下室因大气降水引发的底板局部上浮,进而引发部分柱、梁以及墙体开裂的事故,开展了现场检测鉴定研究,阐明了该事故的上浮原因及结构破坏机理,基于此,开展了该地下室结构工程的永久抗浮处理以及结构加固处理的方法研究,取得了良好的经济和社会效益。本文研究工作对地下室上浮问题具有一定的指导意义。
Underground structure cracking and damage caused by anti-float underground space project, which is a hot and difficult problem in the engineering of recent years. This paper is aimed the accident of the floated basement floor, column, beam, and wall cracking due to the precipitation, at the basement floor of a building in Sichuan. The field detection and identification are carried out. The cause of the floated basement floor and the mechanism of structural damage are clarified. Based on this, the permanent anti floating treatment and structure strengthening treatment of the basement structures are carried out, which achieve good economic and social benefits. And the research work has certain guiding significance to the basement floating problem.
