某粉煤灰砖混结构裂缝成因及加固方法

The genesis and reinforcement method for the cracks in fly ash brick masonry structure

粉煤灰砖作为砖混结构的承重墙体是一个尚待研究的课题 ,以太钢四降压配电室砖混结构为研究对象 ,在现场检测和理论的基础上 ,分析了其裂缝成因 ,并提出了加固方法———钢筋网片加固法 ,从而有效地控制了裂缝的扩展 ,提高了原结构的承载力和整体稳定性。工程实践表明 。

The fly ash brick as bearing wall in brick masonry structure is a topic that should be studied. Taking the brick masonry structure of electrical room as study example the cracks' genesis is analyzed based on spot checking and theoretical analysis. The steel fibre reinforcement method is proposed to control the expedition of cracks efficiently and raise the bearing capacity and integral stability of structure. Practices verify that this is a effective reinforcement method.
