摘要(Abstract)：

介绍襄渝电气化铁路新大成二线隧道爆破掘进基本情况,其中重点是确保紧靠的既有线隧道安全与二线隧道快速爆破掘进所采取的大直径中空直孔掏槽和炮孔水压爆破等一系列技术措施,实际应用取得了令人满意的爆破效果,为今后类似工程提供了成熟的经验。
The paper introduced the blast driving in construction of Xindacheng binary line's tunnel of Xiangyu electric railway in terms of its employment of a series of technological measures such as big diameter straight hole underholing and blasthole water-pressure blasting.The employment resulted in satisfactory blasting effect and provided mature experience for similar engineering.
