BLASTING DEMOLITION OF RUBBLE-MASONRY DAM AND MONITORING TECHNOLOGY

In reconstruction of the rubble masonry dam for Baojixia Diversion Project in Shaanxi,the whole Ⅱ section and partial Ⅵ section of the dam are necessary to be demolished by blasting method In order to avoid the harmful effect of the blasting vibration on near or remained rubble masonry dam bodies,an expansion joint and pre excavated trench are used for separation of blasting vibration,and a slicing demolition method with short hole millisecond blasting is adopted so as to control the charge weight of the maximum delay interval strictly The blasting vibration monitoring and ultrasonic test show that the remained dam bodies are not damaged
