摘　　要：针对城区浅层微动探测精细化高效化的需求,设计一套适用于微动线型台阵的快速探测方案。基于检波器多次覆盖利用和线型台阵高效滚动的观测特点,结合实践经验,设计微动线型台阵快速探测方案输出系统,并利用该系统在城区具体场地开展从数据采集到处理的微动探测实验。结果表明,本文方案能有效提高外业观测效率,为台阵快速布设及平移等提供参考。In response to the demand for refinement and efficiency of microtremor survey in shallow urban areas,we design a rapid detection scheme for microtremor line array.Combined with practices,we design the output system of the fast detection scheme based on multiple coverage utilization of geophones and efficient-rolling observation of line array.This system is adopted in microtremor survey experiments from data acquisition to data processing at specific sites in urban areas.The results show that the scheme effectively enhance the efficiency of field observation and provide references for the rapid layout and translation of array.
