高台阶地形上楼房定向爆破技术探讨

Directional Blasting of Buildings on High Sidestep Landform

介绍了位于 6m高台阶地形上的楼房定向爆破工程实践。该工程通过采用高切口的施工方法 ,首先起爆切口以上的部分 ,最后起爆切口以下部分 ,实现了特殊地形和复杂环境条件下楼房沿不利方向的定向爆破 ,为楼房在结构和地形不对称条件下的定向爆破提供了成功经验。

A directional demolition blasting practice of 6m-high sidestep landform is introduced. The project adopted high cut blasting method. The project adopted from cut to up fire first and fire downstairs finally. The building along disadvantage direction by directional demolition blasting came true under distinguishingly landform and complex environment conditions. The success experiences are provided for directional demolition blasting of building under configuration and landform asymmetry.
