Abstract: 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.

Key words: seismic safety evaluation, long-line engineering sites, active tectonics
