爆破地震效应数据处理影响因素初步研究

PRIMARY RESEARCH ON EFFECT FACTORS FOR THE PROCESSING BLASTING VIBRATION DATA

摘要:

利用爆破及打桩振动地震效应实测数据,讨论了实测数据拟合K值与国家标准规定K值差别较大问题。结果表明:药量对反演安全距离无影响;爆破K值差异较大的主要因素是测点之间传播介质不均匀,近爆源测点介质致密,远离爆源测点介质疏松所致。

Abstract:

According to the measure data of blasting and piling vibration, the difference between fitted K value form the measure data and the specified K value in national standards are discussed in several different aspects. The results show that the explosive quantity has no effect on the inversion of safe distance form measure data in blasting and piling vibration experiments. The main factor that leads to the obvious difference between the two K values, except little influence from the explosive quantity and the error in measure data, is the in-homogeneous medium that is denser near the blasting site and looser far from the blasting site.
