摘要(Abstract):
以隔河岩电站引水隧洞动态监测为范例,论证了安全监测对工程的监控作用和效果。采用爆破振动监测、地震剖面法和同孔法监测相结合,完成隧洞开挖施工中的动态监测的全过程,并对其监测成果进行了分析评价。
Taking the dynamic monitoring of excavating the inlet tunnels of Geheyan Hydropower Plant as an example,the safety monitoring effect on engineering monitoring is discussed in this paperThe monitoring methods of blasting vibrating seismicprofile and the single hole sonic testing are combined to use in the completion of the whole dynamic monitoring process of the construction of excavating the inlet tunnelsThe monitoring result is also analyzed and evaluated
