摘　　要：2018年4-5月,在河北省容城县进行前后两期道路地震学密集台阵观测。观测仪器包括200多个短周期地震仪和22个甚宽频带地震仪。观测台阵跨越高铁、普通铁路、高速公路及普通道路。通过一致性检验和远震波形对短周期地震仪进行台站时钟校正,获得近50万条高铁地震记录。这些地震记录可用于研究高铁或其他道路震源及波场特征,进行浅层及深层地下结构4D成像,为道路安全、地震预测、环境监测、资源和能源探测、地下空间开发利用以及智慧城市建设服务。From April to May 2018, two phases of road seismological intensive array observation(PKU ROSE Array, Peking University-deployed ROed SEismological Array) are implemented in Rongcheng County of Hebei Province. The observation instruments include 200 short-period seismographs and 22 very broad-band seismographs. The observation array spans high-speed and ordinary railway, high-speed and ordinary road. Clock calibration was carried out by consistency test and teleseismic waveform, and nearly 500 thousand high-speed-rail seismic records were obtained. These seismic records can be used to study the sources and wave field characteristics of high-speed rail or other roads, carry out 4 D imaging of shallow and deep underground structures, serving road safety, earthquake prediction, environmental monitoring, resource and energy exploration, underground space development and utilization, and smart city construction.
