摘　　要：在上海高地下水位的软土地区,时常发生地下室底板隆起等事故。以上海嘉定区某一单层地下车库底板隆起事故为例,主要分析底板隆起的原因,明确加固设计原则,合理设计加固方案,强调加固施工的重点、难点。加固施工结束后二年的运行表明:采用锚杆钢管桩加固方式合理,可为类似地下室抗浮设计和施工风险管控提供有益参考。The basement floor heave hazards are frequently encountered in thick soft soils with high groundwater level as urban Shanghai area. This paper presents a case history of the mitigation design and construction of the floor slab heave of a single-story underground garage in Jiading District of Shanghai City. The distress causes, design principles and mitigation construction major steps are also presented in the paper. The observational results from two years after the mitigation construction indicate that the press-in steel pipe piles by using ground anchor as the reaction is both technically sound and cost effective.
