某高层建筑地下消防水池裂缝原因分析与处理

The cracks analysis and treatment of underground fire-fighting pool for a high-rise building

国内外调查资料显示 ,工程实践中结构物由非荷载变形引起的裂缝占裂缝总量的 80 %以上。本文以一高层建筑消防水池裂缝事故为例 ,分析了贮液池施工过程中微膨胀剂的作用机理及裂缝处理方法 ,总结了此类结构实际施工过程中应注意的问题 ,对预防同类结构裂缝具有一定的工程参考价值。

In engineering practice, cracks caused by non-loads and deformation in building is 80% of the total cracks.According to domestic and external data. In this paper, action mechanism of micro-expanding agent, in construction process of liquid store tank, and cracks treatment method are analyzed taking a fire-fighting pool of high-rise building as an example. Problems are summarized in construction process of this kind structure, which is of engineering reference value to prevent cracks in the similar structure.
