摘要
介绍了兰州大尖山核试验监测地震台阵的勘址工作,包括本地区的地质背景、气象条件以及中心建筑(CRF)和各子台建筑的的工程地质情况。该台阵投入观测后表明:台阵所在地区的气象、地质条件等观测环境完全满足全面禁止核试验条约组织国际监测系统(CTBTO/MS)勘选台阵的要求。兰州大尖山地震台阵的建成,进一步提高了甘肃省兰州市及周边地区微震活动的监测能力。
In this paper, the site survey for Dajian Mountain Seismic Array in Lanzhou is introduced. The job includs the conditions of geology and meteorology of the array site, the engineering geological conditions of center recording facility (CRF) and 9 substations. The observation environment and design of the array conform to with the demands of site survey from CTBTO/MS, and the array works very well in operating. The monitor capability of micro-seismic activity in Lanzhou city and adjacent area will also be enhanced.
