摘要(Abstract)：
厦门324国道改线工程中的竹仔坑隧道从竹仔坑水库侧下方穿过,在隧道爆破施工过程中,采用短进尺、二台阶五步法、二级楔形掏槽及光面爆破等技术,实现了爆破目标,隧道围岩稳定且未损害水库堤坝,确保了隧道施工安全,可为类似工程提供参考。
Zhuzaikeng Tunnel of Xiamen 324th national road modification project went through the reservoir.The short footage,the two benches and five steps method,secondary double wedge cut and smooth blasting technology were adopted in the construction process of tunnel blasting,and the blasting goal was fulfilled that tunnel surrounding rock was stable and the reservoir dam did not been damaged to ensure the safety of tunnel construction.It could provide a reference for similar engineerings.
