Abstract: In this paper, the fundamental theory and basic principle of the seismotectonic approach to evaluation of design basis ground motion are introduced firstly, then the difference between the new Safety Guide of IAEA and the old one is anlysed, The defects in this method are discussed, and the actual problems which in using this method appear in nuclear power plants siting are discussed too. Finally, the development and improvement of the seismotectonic approach are suggested.

Key words: Seismotectonic apporach, Seismotectonic province, Seismogenic structure, Maximum potential earthquake

摘要： 阐述了核电厂选址工作中,确定设计基准地震动的"地震构造法"的构成及其基本原则,就其在国际原子能机构(IAEA)颁布的新旧两版"核安全导则"(1979年版、1991年版)中的异同进行了对比分析,并探讨了"地震构造法"在实际工作中存在的问题,以及对它的改进。
