摘要
文章以新建库鲁塔格隧道爆破施工为例,通过进行爆破振动测试,分析爆破施工过程中既有隧道的爆破振动速度与微应变之间的相互关系,研究新建隧道爆破施工对临近既有隧道的影响。
The article uses the blasting operation of the newly established Kulutage Tunnel as an example to study and analyze the side effects of blasting operations to nearby existing tunnels.The blasting vibration testing was used during the tests and correlation between the vibrating speed and micro-strain is analyzed based on the test results.
