摘　　要：同震位移研究对地震过程模拟、地震机理研究和未来地震危险区评价具有重要意义。作者系统地梳理和总结了多种同震位移预测模型,包括Wells模型、陈培善模型、dmax(M)模型、Segall模型和Okada模型,并对各种模型的原理和理论公式进行了简要总结回顾,比较了各模型的优缺点及适用条件。同时作者将21世纪以来国内具有详细地表水平破裂的地震信息作为计算参数,对比分析了3种常用模型的预测结果,为日后选定不同条件下的同震位移场分布研究提供参考。The study of coseismic displacement is of great significance to the simulation of earthquake process,the study of seismic mechanism and the assessment of future seismic risk zones.The authors systematically review and summarize the variety of coseismic displacement prediction attenuation models,including Wells model,Pei-shan Chen model,dmax(M)model,Segall model and Okada model,and make a brief summary of the principles and theoretical formulae of all kinds of model,comparing the advantages and disadvantages and suitable conditions of each model.At the same time,the authors take the data,which comes from seismic information of surface ruptures since the 21 st century,as parameters for calculation and compare the prediction results of three common models in order to provide a reference for research of coseismic displacement field distribution under different conditions.
