Abstract:
Because of the tunnel's excavating at Karst area has a direct influence on a Karst cave wall rocks and the safety performance of excavating, so it is necessary to monitor the vibration resulted from blasting in Baixugong tunnel at Karst area. Through the statistical analysis of vibration's peak value of some particles' on Karst cave wall, the attenuation law of vibration wave's transiting in a Karst cave wall was studied. When a Karst cave is exposed to the blasting in a nearby tunnel, the safety peak value of vibration of particls on Karst cave wall was presented. The results show that the radial vibration of the wall is smaller, the vertical vibration and shear vibration are about equal especially the blasting is controlled to be smaller and smaller. 3 tabs, 5 figs, 10 refs.
