Experimental Study on Collapse Vibration Simulation of Demolition Blasting

摘要：

Using the reinforced concrete telegraph pole and big mechanical equipment, die paper simulates the collapse touchdown course of chimney for finding out collapse vibrations hazards of demolition blasting. During the collapsing process, we arrange two testing lines and use two kinds of testing equipment to collect vibration signal. After analyzing the testing result, we have gain valuable conclusion. At he same time, we have excavate the vibration absorption ditch and soft ground media around collapsing regional in order to studying the spread and attenuation rule of collapse seismic wave and the absorbing vibration effect of vibration absorption ditch.
