三峡库区望霞危岩体削方爆破振动测试分析
|
摘要
为确定三峡库区望霞危岩体爆破治理的地震波传播规律,评价其对附近坡体和建筑物的影响,对爆破治理工程进行了现场振动监测。根据现场测试数据的统计和回归分析,参考萨道夫斯基公式,得到了表征爆破地震波传播规律的经验公式。结果表明,爆破振动速度均小于安全规程规定值,振动对保留岩体及周边建筑影响有限,为后续治理工程控制爆破振动效应提供了理论依据。
To study the propagation behavior of seismic wave induced by Wangxia dangerous rock mass blasting in the Three Gorges Reservoir and to evaluate the influence on buildings and slope nearby,the field blasting vibration was monitored.Based on the statistics and regression analysis of the field data and reference Sadaovsk formula,the experience formula characterizing the propagation behavior of blasting seismic wave was figured out.Results show that the blasting vibration velocity was less than the safety value and made little effect on remained rockmass and surrounding buildings,which helps to control the blasting vibration effect on the following treating project.
