【摘要】 为了在强震台址勘选、台站观测环境保护工作中对泵房、火车站、采石场爆破这三类干扰源的避让提供定量参考依据,通过实地测试,探讨了这三种干扰源的振动衰减关系。研究认为预警与固定观测台站离开11kW泵房的距离应不小于69m;离开(客货低速)铁路线的距离应不小于228m;离开采石场的距离应不小于723m。烈度速报台站离开泵房的距离应不小于19m;离开铁路线的距离应不小于156m,离开采石场的距离应不小于428m。更多还原

【Abstract】 In order to provide quantitative reference for avoiding interference sources such as pump,train station and quarry blasting in strong motion station establishing and station environmental protection work,some tests on site are done and the vibration attenuation relationships of these three interference sources are discussed.The studies suggest that the distance from the station for early warning and fixed observation to pump should be more than 69 m,to train line(low-speed for passenger and freight) should be more than 228 m,and to quarry should be more than 723 m.The distance from the station for quick report to pump should be more than 19 m,to train line should be more than 156 m,and to quarry should be 428 m.更多还原
