| 摘 要： | 以福建省罗源县正在建设的龟屿隧道爆破工程为例,分析了隧道爆破地震波的传播规律和对毗邻大黄鱼育苗池的水中声场环境的影响.研究结果表明:(1)爆破作业将显著地增加毗邻大黄鱼育苗池的水中声强(比未爆破前的水中声强高约60～80 dB),强度的增加与爆破药量成正比,与爆点的距离成反比,且距离的影响远大于爆破药量的影响;(2)在...

| Abstract: | Underwater sound effects generated by tunnel-explosion were studied and an observation was performed to monitor the underwater sound pressure in Pseudosciaena crocea's breeding pond when Guiyu tunnel blast engineering occurred thither coastal harbor in Luoyuan County,Fujian Province.Based on acoustic theory of transmission and reflection on solid-fluid interface,the results show that blasting seismic wave makes impact on underwater environment through two kinds of sound transmitted paths.The underwater soun... |
