水库坝区竖井开挖爆破技术及振动测试分析
|
摘要
结合水库坝区竖井开挖爆破的施工实际,对竖井的爆破参数进行了设计,阐述了爆破振动的测试方法并对测试结果进行了分析。从实测典型波形图看,各段波峰基本按设计的微差间隔时间分隔开,由于雷管跳段使用,所以没有出现明显的振动峰值叠加现象,其爆破分段是合理的。测得的最大振动速度为2.68 cm/s,爆破振动不会对主要建(构)筑物产生影响。
In the light of its practical construction,the blasting parameters of the shaft were designed,and the monitoring method and results of shaft blasting excavation in the reservoir are introduced.From the typical waveform graph,different wave peaks are separated as the designed millisecond delay intervals.The blasting sections are reasonable because no peak overlapping was found due to sectional blasting.The maximum vibration speed is 2.68cm/s,therefore the blasting vibration has no impact on the dam.
