一、前言近年来,随着地震预报和工程建设的需要,活断层研究受到人们越来越多的关注,并且在许多方面取得重大进展。目前国内外发展比较成熟的活动断层研究的新技术新方法,大致可分为以下几类：①构造地质—地貌学方法(包括航空和遥感地质判译)；②第四系沉积和相分析：③新年代学测定；④槽探工程：⑤地球物理和地球化学探测；⑥信息科学中的计算机技术(如三维数字仿真地形模型)的应用等。本文应用上述相关技 I. Introduction In recent years, with the needs of earthquake prediction and engineering construction, active fault research has drawn more and more attention from people and made great progress in many aspects. At present, the new techniques and new methods of active fault research developed at home and abroad can be divided into the following categories: (1) tectono-geomorphology (including geo-interpretation of aviation and remote sensing), (2) sedimentation and facies analysis of Quaternary: ③ New Chronology Determination; ④ trench exploration project: ⑤ geophysical and geochemical exploration; ⑥ computer science in information science (such as three-dimensional digital terrain simulation model) applications. This article applies the above related techniques
