Abstract: In this paper, site effect on earthquake hazard, its general principle and approach of evaluation is discussed in five sections: evaluation of earthquake hazard, seismic hazard analysis, zoning geologic unite, analysis of ground motion response and synthetic classification of active fault in engineering. Some considerations and experience are presented from engineering practice.

Key words: Site effect on earthquake hazard, Evaluation of earthquake hazard, Analysis of earthquake hazard, Microzonation, Seismo-engineering-geology unite, Seismo-engineering evaluation of fault

摘要： 本文从场地地震危险性评价,地震危险性概率分析、场地地震工程地质单元划分、地震反应分析、活断层工程分类等五个方面、论述场地地震效应及其预测中基本原理和方法。根据工程地震危险性评价和分析、地震小区划等地震工程实践,对场地地震效应及其预测提供一些基本考虑和经验。
