中国长线工程场地地震安全性评价工作中的活动构造问题

长线工程场地一般都得穿经活动构造带,因而活动构造研究在该类场地的地震安全性评价工作中尤为重要。为此,文中对长线工程场地对地震安全性评价工作的要求和活动构造的研究现状进行了总结和分析,在此基础上,提出了长线场地地震安全性评价工作中活动构造研究宜开展的研究内容、技术指标、技术路径和成果提交等工作要点。最后,对长线场地震安全性评价工作中活动构造研究目前存在的一些问题进行了初步的分析和探讨

ACTIVE TECTONIC RESEARCH FOR SEISMIC SAFETY EVALUATION OF LONG-LINE ENGINEERING SITES IN CHINA

Long line engineering sites usually have to pass through some active tectonics, so that the research of active tectonics is of great importance to seismic safety evaluation of this sort of site. In this paper, basing on the summarization and analysis of the requirements for seismic safety evaluation of long line engineering sites and the present situation of active tectonics research, we propose the focal points of active tectonics research for seismic safety evaluation of long line engineering sites, including research contents, technical target and routes, and the submission of the achievements, etc. Furthermore, we make a preliminary analysis and discussion about some problems existing in the present day active tectonics research for seismic safety evaluation of long line engineering sites.
