地下设备室上浮事故案例分析

On analysis of up-floating accidents of underground equipment rooms

以某工业厂房地下设备室上浮事故为例,阐述了该设备室发生上浮事故的原因,通过抗浮验算,分析了设备室在浮起回落过程中的结构完整性,评估了后续沉降对结构的影响,并提出了具体的抗浮设计措施,从而减小或消除水浮力对地下设备室的不利影响。

Taking the up-floating accidents at the underground equipment rooms at some industrial workshop as the example, the paper illustrates the reasons for the up-floating accidents at the rooms, analyzes the structural wholeness of the rooms in the up-floating and falling back process ac- cording to the anti-floating calculation, evaluates the influence of the following settlement on the structures, and points out the anti-floating design measures, so as to relieve the unfavorable influence of the buoyancy on the equipment rooms.
