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 paperThe monitoring methods of blasting vibrating seismicprofile 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 tunnelsThe monitoring result is also analyzed and evaluated
