摘　　要：上海某一层地下室在结构封顶后发现地下室底板柱脚出现开裂冒水情况,发现问题后施工单位对地下一层柱脚根部周边进行了初步封堵处理,之后发现局部底板有上浮、隆起变形现象,并且少数柱根仍有冒水情况。为查明地下一层底板开裂、冒水原因,对该一层地下室区域进行专项检测。通过现场检测、复核验算、分析评估并提出处理建议,确保地下室正常使用,为后续类似工程问题提供参考依据。A sub-basement floor in a building in Shanghai was found to have cracked and been leaking water at the base of the columns after the structure had been topped off. After the problem was discovered, the construction unit carried out initial sealing work around the base of the columns. However, it was later found that some parts of the floor had risen and deformed, and that a few column bases were still leaking. In order to investigate the cause of the cracking and leaking in the sub-basement floor of the first level, a special inspection was carried out in the area. Through on-site inspections, calculations, analysis, and evaluation, and by providing recommendations for treatment, this report aims to ensure the safe use of the underground space and provide reference for similar projects in the future.
