Construction Of Active Fault Database In Weinan City

How to store and manage the active fault detective data scientifically and effectively,how to make it play a role in predicting earthquakes、earthquake monitoring and seismic fortification,these need us to address the important issues in active fault surveying work.Based on the Weinan urban active fault detection project,drawing the experience from Xi’an,Xianyang City,Baoji City,Hanzhong City’s construction of active fault database,referring to the active fault detection system,this paper analyzes the characteristics of the three stages of pre-Preparation,field investigation and analysis.Under the premise of clarifying the relationship between the exploration of the subject,all topics are necessary to split and merge through the classification,selection and integration;On the basis of ArcGIS geographic information system platform,using File Geodatabase data model,the paper gives the library structure table,builds professional active faults database and database of active faults composed of 7 thematic databases,including regional tectonic thematic mapping results of 250 thousand scale,deep seismic detection projects,the active fault survey projects,geological mapping projects of 10 thousand scale,shallow seismic control detection projects,structure distribution of thematic map results of 50 thousand scale,and the seismic hazard thematic analysis results.The effective management of the data of active fault detection in Weinan is realized,which provides a scientific basis for urban construction,land use,development planning and seismic fortification,for all levels of government departments and the community to provide consulting services.On this basis,the paper puts forward the strategy of constructing the data collection and data synchronization,and designs the standardized form of data acquisition,which is a useful attempt to ensure the progress and quality of the database construction.
