Abstract:

The goal of the exploration to active fault is to understand its activities,relative parameters,the spatial distribution characteristics and its deep structures. There're three major stages for active fault exploration,namely, preparation stage,exploration stage and analysis stage. The construction of the database for each of these stages has different focus.
Based on the review of other articles about the development of active Fault database from international sources,the paper introduces the construction of databases based on the Technological System of China Earthquake Active fault Exploration project. And along with the development and implementation of the projects such as ‘Seismic Risk Assessment of Active fault in Key Earthquake Monitoring Areas in China’,‘China Earthquake Active Fault Exploration’, so on,database templates corresponding to each of the stages of active fault exploration are worked out according to the design idea,architecture and implementation of ArcGIS-based active fault database and the work procedure for active fault exploration. The main functions of the bulk storage software and data quality monitoring software developed for the construction of the database are introduced.
Due to the numerous data and the extensive sources as well as the complexity of the data acquisition during the building of database,there are chances to have either manual or systemic errors,and moreover,the data quality might be impacted,resulting in a database failing to represent the real activities of the active faults. On the other hand,the data stored in the database lacks consistency and integrity,thus,the database is ineffective and opposite to the original intention of its construction. The paper analyzes the main data sources used to establish the active fault database and the causes for generating low quality data,and discusses the advantages for building the active fault database simultaneously along with the implementation of active fault exploration.

摘要：

在回顾国内外活动断层数据库发展概况的基础上,介绍了基于 "中国地震活动断层探测技术系统"项目建设,并随着 "中国地震重点监视防御区活动断层地震危险性评价"、"中国地震活断层探察" 等项目的开展不断完善的,基于ArcGIS的活动构造数据库的设计理念, 基于活动断层探察的工作流程研究设计的活动构造数据库模板主体框架与建设方案,为活动构造数据库建设配套研发的数据批量入库软件、数据质量检测软件; 讨论了活动构造数据库建设过程中出现数据偏差的主要问题的根源,分析了数据库建设对活动断层探察工作精细化、标准化的促进作用,及与活动断层探察工作同期开展数据库建设的益处。
