[Abstract]:China is a earthquake-prone country, for the densely populated countries, we should do a good job in earthquake prevention and disaster reduction, which will directly affect our economic development and social stability. Therefore, it is necessary to take all kinds of effective measures to reduce the loss of earthquake disaster as far as possible, and to use advanced scientific and technological means in earthquake disaster prevention and seismic disaster reduction, which is the development trend of earthquake engineering and soil dynamics. With the rapid development of information technology in modern society, GIS (Geographic Information system), GPS (Global Positioning system), RS (remote Sensing) is used to obtain, The processing and application of spatial data related to the earth's natural and human factors will provide new impetus for the development of seismic engineering and soil dynamics. Based on the advanced ArcGIS technology, this paper studies the problems in geotechnical seismic engineering, develops the regional site seismic stability and liquefaction evaluation technology, taking Tangshan and its southern suburbs as an example, preliminarily forms a geotechnical damage zoning system based on ArcGIS. It provides the foundation for further research and engineering application in the future. The main work and achievements of this paper are as follows: 1. This paper expounds the structure system and application method of ArcGIS10.0, analyzes and compares the advantages and disadvantages of ArcGIS and MAPGIS, and emphatically studies the construction method of Geodatabase, a database geographic database of ArcGIS10.0, taking the making process of geomorphological thematic map as an example. The whole process of production is realized. 2. Based on ArcGIS10.0, taking Tangshan and its southern suburb as an example, the flow chart and digitized and visualized technical route of site seismic stability evaluation method are put forward. 3. In the study of seismic stability in Tangshan and its southern suburbs, five factors are considered, such as faults, landforms, distribution of groundwater table depth, dynamic coefficient and site type. A database corresponding to these five factors is established in ArcGIS. The automatic superposition of five element layers is realized, and the seismic stability potential map of Tangshan and its southern suburbs is given. It overcomes the shortcoming that MAPGIS can not be classified automatically, saves time and improves efficiency greatly. The data of 65 boreholes in Tangshan and its southern suburbs were collected and sorted, and the establishment of borehole graphic database and attribute database on ArcGIS10.0 was completed. According to borehole data, two methods are used to discriminate liquefaction. By using Kriging interpolation method, the liquefaction of unknown areas is obtained, and the liquefaction zoning map of Tangshan and its southern suburbs is given. 5. Using ArcGIS Engine and VB to carry out integrated secondary development, taking Tangshan and its southern suburbs as examples, the preliminary design of geotechnical seismic hazard zoning system including site seismic stability analysis, liquefaction zoning analysis and borehole management is realized, which includes three main modules: site seismic stability analysis, liquefaction zoning analysis and borehole management.
