Experimental research on vibration caused by blasting for dam base excavation engineering of Lizhou Hydropower Station

LI Rongguo

Abstract

Based on research and analysis on the data of blasting experiment of dam abutment of Lizhou Hydropower Station,the attenuation laws of blasting vibration suitable to special geology and geography conditions of this hydropower station were obtained;and the blasting control parameters for excavation engineering of dam base surface were provided.Simultaneously,according to site observed results,the reference for forecast of blasting vibration velocity and security checking was provided.
