Abstract

Model test studies based on the similarity theory was conducted to solve the problem of vibration effect of tunnel surrounding rock under push-type cyclic blasting excavation. The model was constructed with a ratio of 1:15. By simulating the tunnel excavation of push-type cyclic blasting, the influence of the change of blasting parameter on vibration effect was explored. The relationship between the damage evolution of surrounding rock and blasting times was established. The following test results can be obtained: When the maximum section dose was roughly same, the influence of the initiation section number on the dielectric coefficient (K) of Sodev formula was very small, and on the contrary to the attenuation coefficient ( ) of Sodev formula.
