新柳林河隧道爆破振动监测及分析

Monitoring and Analysis on Blasting Vibration of New Liulinhe Tunnel

结合太兴铁路太静段工程TXXS-1标段新柳林河隧道的实际工程,对新建隧道光面爆破开挖而产生的爆炸振速进行监测与分析,并得到振速预测公式。在施工中,通过及时调整爆破参数来控制爆破振速,保证了隧道掘进施工的安全。

Combined with the practical project of New Liulinhe tunnel at Taijing TXXS-1sector in Taixing railroad,monitoring and analysis on blasting vibration of new tunnel caused by smooth blasting were carried out and a prediction formula of vibration velocity was achieved.Construction security in roadway excavation was guaranteed by adjusting blasting parameters timely for controlling vibration velocity.
