小洞穴爆破在国外某边坡处理中的应用

Application of Small Chamber Blasting on one Abroad Side Slope Treatment

山区公路在施工工程中常常会因受到地形条件、水文地质、交运运输困难及施工操作困难等不利条件,应选择合理的施工方法。针对修建公路时遇到的大面积开裂边坡处理难题,提出采用一种小洞穴爆破进行处理的措施,解决了山区公路施工难的问题,且边坡在爆破下滑后呈现的边坡面比较稳定,悬挂危岩的数量较少。

Construction works of mountain roads often affected by terrain conditions,hydrogeology,difficulties in transportation,difficulties in construction operation and the other disadvantageous conditions,therefore the reasonable construction method shall be selected.It is proposed to adopt small chamber blasting for problem that extensive cracked side slopes in road construction,therefore,the problem can be solved,and the treated slopes were relatively stable after blasting and sliding,there are few hanging dangerous rocks there.
