摘　　要：由于某些地区地下水位的上升,一些地下室出现了如漏水、起拱甚至整体上浮等不同程度的抗浮问题。结合某项目的地下室抗浮事故处理,分析了事故出现的原因,并根据两种抗拔桩型的对比试验,最终确定选用了内插钢管的旋喷桩作为抗拔桩。实践结果表明,该处理方法有效地解决了该地下室的抗浮事故。Due to the rise of groundwater level, in some areas, many podium basements have encountered various anti-floating problems, such as water leakage, slab-arching and even overall floating. This paper combines the anti-floating accident treatment of a basement in a project, analyzes the cause of the accident, and based on the comparison test of two types of uplift piles, finally selects the jet grouting pile with the inserted steel pipe as the uplift pile. This treatment effectively solves the anti-floating accident of the basement.
