［摘要］某地下车库发生局部抗浮失稳，造成部分钢筋混凝土柱产生剪切压弯破坏,对其破坏原因及破坏形态进行了深入分析和简化计算。采用三维简化计算模型的计算结果与实际情况吻合较好，验证了简化模型的合理性。针对该抗浮具体问题提出了开泄压孔及临时支撑的现场应急处理方案，并介绍了后续加固方法。

Abstract:Some reinforced concrete columns of an underground garage structure were seriously destroyed by local anti-uplift instability. The reasons and failure form were analyzed, and simplified calculation was given. The calculation of three-dimensional model were in good agreement with the actual instance, so the simplified model is reasonable.For the specific issue of local anti-uplift, on-site emergency treatment and strengthening methods were introduced.
Keywords:underground garage； local anti-uplift； failure form； emergency plan； strengthening treatment
