| 摘 要： | 通过对宜泸高速连接宜叙高速江安段胜利互通立交陡坡危石的分析,针对该处复杂的爆破环境和特殊要求,基于爆堆重心线与抵抗线相干性及爆破块度分布特征与孔网参数、装药结构、起爆顺序相干性等控制爆破理论,对立交处陡坡危石的爆破排险,提出了合适、简单、易操作的爆破方案,方案实施后,取得了良好的效果。

Study on Design for Danger Removal by Blasting of Abrupt Slope and Dangerous Rock of Shengli Interchange |
| |
| Abstract: | Overhanging rocks over the Shengli interchange between the Yibin-Luzhou expressway and the connecting line to the Yibin-Xuyong expressway is analyzed. Aimed at the complicated blasting environment and special requirements of the interchange based on the coherence of the gravity center line and resistance line of blasting muck pile and the control theory of blasting like distribution characteristics of blasting lumpiness, hole pattern parameters, loaded constitution and blasting order coherence, etc., putting forward applicable and simple blasting program which is easy to operate. It is proved to be with good effect after the scheme is implemented. |
