[Abstract]:Earthquake prediction is still an exploratory research project , especially for medium , short - term or pre - earthquake prediction , which is far from practical . Some scholars have doubts about the realization of earthquake prediction , and have reservations about using administrative means to organize earthquake prediction .

The scientific premise of earthquake prediction is to know the physical process of earthquake inoculation and occurrence , including the abnormal change of physical and mechanical properties of earth medium . However , there are few factors affecting the genesis and the occurrence of earthquakes .

This paper deals with the problem of how to comprehensively utilize the fault deformation data to study the prediction of earthquake prediction under the existing conditions . In view of the multi - source of deformation anomaly in fault analysis , it is considered that the site basic information existing in the field basic information management and use of the northeast margin of Qinghai - Tibet block is incomplete , and the multi - system paper medium is stored , inconvenient to query and use ;
The fault monitoring data of the site is separated from the relevant basic geographic information and is not convenient for comprehensive analysis and so on . The method of establishing the foundation database of the cross - fault site is discussed , and the basic information management system of the cross - fault measurement site based on GIS is developed to improve the management , analysis and utilization of the cross - fault deformation monitoring information .

The main contents are as follows :

( 1 ) Collection and arrangement of basic data of cross - fault site

In addition to the basic information of fault and the original data of each period fault , the cross - fault site basic data includes site survey , geographical environment , topographic map , climate , temperature , site geological background , historical earthquakes around the site , and other basic information , and the possible factors of deformation anomaly and influence conditions and dynamics are studied in order to improve the scientific and accuracy of earthquake analysis and prediction .

( 2 ) Design of Cross - fault Site Database Model

The model is established on the basis of data . The data model includes the vector data model , the grid data model and the lost - grid integration model . Based on the analysis of the actual application requirement of the data of the cross - fault site and the related data specification , we chose the relational database as the base of the database construction theory , designed the cross - fault site database model , and optimized the database according to the actual situation , and improved the practicability of the cross - fault site database .

( 3 ) Establishment of cross - fault site database

according to the established database model , data processing and integration of the collected cross - fault site data are carried out , and an independent cross - fault site database is finally established .

( 4 ) Development of cross - fault site database management system

Based on VS2010 + ArcEngine development environment , under the requirement of practical function , the design of database management system of cross - fault site is realized , which provides friendly interactive interface for users .

The salient features of the above database are :

For the first time , a cross - fault basic information management system is established , which has great help for improving the depth and breadth of fault deformation analysis and the scientific nature and accuracy of anomaly analysis .

( 2 ) the organic combination of cross - fault site database and mature geographic information system .
In addition , reference is provided for the design of other professional databases .
