摘要
研究收集了宁夏全区及周边地区的爆破258次,对这些爆破丛集发生的地点进行现场落实,收集爆破类型、爆破时间、炸药量等资料。从爆破分布、不同类型爆破波形特征、场地及传播路径对爆破衰减影响等三方面进行研究。结果表明:爆破的波形记录特征不仅和爆破的类型有关,不同爆破场地及波传播路径在初动、周期、衰减速度均有不同表现,并解析了存在差别的原因与台站场地响应有关。
We collected 258 explosions data in Ningxia and its surrounding areas, and surveyed the quantitative-explosion area in the field to get the types, time and explosive weight of these explosions. According to the distribution, waveform and attenuation influence from site and propagation, the following results are obtained. The waveform features of explosion are not related only to the type of it. Different site and propagation exist in initial motion, period and attenuating rate, and these differences are related to site response.
