摘要
针对在建简浦高速公路长秋山隧道穿越瓦斯频繁突出的龙泉山脉的施工难题,运用现场调查、理论分析、最优化方法等对隧道工程条件和瓦斯涌出风险进行了分析,提出了瓦斯条件下的总体爆破原则、爆破方案及参数,确定了爆破施工工艺。实践表明,所提出的瓦斯隧道爆破施工系列方案及技术可以获得较好的爆破效果并能够确保工程安全和进度。
According to the construction difficulty of Jianpu expressway Changqiushan tunnel passing through Longquan mountains where gas frequently happens, the tunnel engineering conditions and gas emission risk were analyzed by using the method of field investigation, theoretical analysis and optimization method. The general blasting principle, blasting scheme and parameters in gas condition were presented and the blasting construction technology was determined. The results showed that the series of blasting and construction schemes for gas tunnel could obtain good blasting effect and ensure the safety and progress of the project.
