Abstract
The development and application of seismic technology in civil engineering structures is of great significance to extend the service life of buildings and improve the overall quality of buildings, so it is necessary to further strengthen the research on it. Geographic Information System (GIS) is a new subject integrating computer science, informatics, geography and other sciences. Because of its rapid and convenient management of massive data, GIS has been widely used in the fields of resource development, environmental protection, urban planning and construction, disaster monitoring and evaluation, etc. GIS is used to manage and analyze the data, and the damage detection module in the system is used to realize the structural damage identification. And use that special thematic analysis function of GIS to display the data on the map in the form of statistical graph, so that users can find the damage position more directly and clearly.
Highlights
Earthquake is the most serious sudden natural disaster that endangers people's lives and property
At present, it is necessary to change the structural design method and adopt the elastic design method to ensure that the building will not be damaged in the event of a low-grade earthquake, and that the building can be kept intact in the event of a moderate earthquake through repair, and that the building will not collapse in the event of a large earthquake [5,6], so that the loss caused by the earthquake can be controlled within the minimum range
3.1 Improve the seismic performance level of civil engineering First of all, when we do the site selection design, we need to do a good job of research and survey for the selection of the ground in civil engineering, and we need to study all aspects of the stability, firmness and hardness of the ground
Summary
Earthquake is the most serious sudden natural disaster that endangers people's lives and property. Geographic Information System (GIS) is a relatively mature computer system developed in recent ten years, which is being widely used by various departments to establish practical systems [2,3] It can conveniently collect, analyze, manage and output spatial data. Applying GIS to urban earthquake disaster prevention, we can establish practical analysis model and make loss assessment and emergency plan in time by controlling spatial geographic information, lifeline engineering, buildings and structures and other disaster relief facilities, improving disaster relief efficiency and saving precious time for earthquake relief. 2.1 Construction site of the project When an earthquake occurs, different construction sites suffer different degrees of earthquake damage, so it is important to choose their construction sites in the process of civil engineering construction, and this is an important factor that directly affects the seismic effect of this engineering construction. At present, it is necessary to change the structural design method and adopt the elastic design method to ensure that the building will not be damaged in the event of a low-grade earthquake, and that the building can be kept intact in the event of a moderate earthquake through repair, and that the building will not collapse in the event of a large earthquake [5,6], so that the loss caused by the earthquake can be controlled within the minimum range
