摘　　要：针对某坡地建筑地下室在施工期间发生的抗浮安全事故,进行了事故成因分析。阐明了施工期间抗浮措施的必要性,以及渗流水压力对坡地建筑基础底板浮托作用的不可忽视性。并根据工程具体情况采取了排水盲沟降低地下水位、增加底板抗浮承载力等相关处理措施,相关处理措施的有效性得到了验证,进而总结了抗浮设计中应特别关注的问题。The thesis analyzes the basement anti-floating accident causes of the sloping building during the construction period, clarifies the necessity of anti-floating measures during the construction period and the non-negligible effect of seepage water pressure on the floating support of the foundation slab of a sloping building. According to the specific conditions of the project, processing measures including lowering drainage blind trench to the groundwater level, increasing the anti-floating bearing capacity of the foundation slab are adopted. The effectiveness of the relevant treatment measures has been verified, which in turn summarizes the issues that should be of particular concern in the design of anti-floating.
