福建沿海港口建设中的活动断裂与地震安全

Active faults and seismic safety in Fujian coastal harbour construction

本文研究了福建沿海港湾的活动断裂与地震安全问题。结果表明，福 建沿海地区ＮＥ、ＮＷ向断裂发育，晚更新世以来都具有明显的张性活动，严格地控 制了沿海港湾的形成和发育；福建沿海地区历史上地震活动频繁，发生过多次破坏性 地震。因此，在港口建设中应认真研究活动断裂与地震安全问题。

This paper studies the active faults and seismic safety problems in the Fujian coastal harbour construction. The result shows that the fault develops along NE and NW directions in the Fujian coastal area. With an obvious tension fault activity since Late Pleistocene epoch, and formation and development of Fujian coastal harbour the development was con trolled. Historical earthquake activities in Fujian coastal area are frequently and destructive earthquakes repeatedly occurred. Therefore, active faults and seismic safety problems of the harbour construction ought to be studied in depth.
