In this paper, based on the safety monitoring of tunnel excavation blasting in the Tai'an pumped storage power station project, combined with volume test data, the subject investigated is vibration field, which is caused by tunnel excavation blasting. The main work is:Firstly, the influencing factors of blasting seismic wave's transmission and attenuation are analyzed theoretically; then through regression analysis on the field data by the least square methods, we get the velocity attenuation law. The featu...
