摘要
京福高速公路徐州市铜山县某段经过山丘 ,路堑边坡高度达 2 5～ 5 0m ,岩体节理发育。为确保边坡稳定 ,降低工程成本 ,采用了预裂爆破技术。介绍该工程边坡预裂爆破的技术参数 ,起爆技术及爆破效果。
The part of Jing Fu Express Highway is through mountain in Tongshan county of Xuzhou city ,its slope is up to 25 50 meters and full of crack rockmass. In order to keep slope steady and lower cost,the Pre splitting blasting technique was used. The pre splitting blasting,technical parameter, firing method and blasting effect of the project are introduced.
