摘要
为完整记录岩塞爆破过程,查明爆破对隧洞衬砌、检修竖井及闸门和水生生物的影响情况,针对长距离有压输水隧洞的工程特点,采用预埋的振动、加速度、压力传感器对爆破地震效应、冲击效应进行实时动态监测,并结合隧洞安全监测项目进行爆破前后的静态监测。通过以上监测方案,全面系统的测得了爆破前后产生的各项数据,为评价构筑物及设备的安全状况和对水生生物的影响情况提供可靠依据。
Full records for rock plug blasting process,find out the influence to overhaul shaft,tunnel lining,gate and aquatic organisms by blasting.According to the characteristics of long distance with pressure water conveyance tunnel,Using embedded vibration,acceleration,pressure sensor,blasting earthquake effect,impact effect are being monitored for real-time and combined with the tunnel safety monitoring items of static monitoring before and after blasting,comprehensive system data have measured before and after blasting,for evaluating the safety of the structures and equipment condition and the effects on aquatic organisms to provide reliable basis.
