［摘要］某地下車庫發(fā)生局部抗浮失穩(wěn)，造成部分鋼筋混凝土柱產(chǎn)生剪切壓彎破壞,對其破壞原因及破壞形態(tài)進行了深入分析和簡化計算。采用三維簡化計算模型的計算結(jié)果與實際情況吻合較好，驗證了簡化模型的合理性。針對該抗浮具體問題提出了開泄壓孔及臨時支撐的現(xiàn)場應(yīng)急處理方案，并介紹了后續(xù)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
