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。

Abstract:

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 4D 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.

Key words: road seismology, seismic observation array, seismic source, smart city
