摘要
在太长高速公路的砂岩边坡中实施了光面爆破 ,从爆破效果看 ,对于松软、完整性差的岩体 ,只要参数选择得当 ,依然可以获得良好的光爆效果。同时 ,文章分析总结了该地质条件下砂岩合理的光面爆破参数和施工工艺 ,对同类工程具有一定的参考价值。
The smooth blasting has been applied to sandstone slopes of Tai Chang Expressway.The results showed that once the parameters rationally selected,excellent smooth blasting results could be obtained in the soft and poor completed rock mass.Meanwhile,the paper analyzed and summarized the rational smooth blasting parameters and construction technology for the sandstone under the geological conditions, which would have a certain reference value to the same project.
