摘要

为了降低爆破振动对周围介质的损伤,对丹东蒲石河抽水蓄能电站下水库坝基爆破进行了振动监测。通常现场影响爆破振动的因素较为复杂,文中分析了爆破监测结果,确定了K、α取值,给出了最大单段药量公式的修正参数λ,并提出了降低炸药单耗等合理的建议,可以有效指导爆破施工。
To reduce the blast-induced damage to surrounding media,excavation blasting vibration of Lower Reservoir dam foundation of DanDong Pushihe Pumped Storage Station was monitored.Usually the factors that influences the blasting vibration are complex.In this paper the results of blasting monitoring are analyzed and K and α are evaluated.The correction coefficient λ of the formula of maximum charge in one delay time is proposed,and some rational suggestions,for instance,to reduce specific charge are put forward which may guide blasting construction effectively.
