GIS-BASED ANALYSIS OF FAULT PATTERNS IN URBAN AREAS (A CASE STUDY OF IRKUTSK CITY)
Nowadays people have just started using geoinformation technologies for dimensional analysis of urban area faults. This paper studies the capabilities of GIS in modeling of faults and fault-block structures located in urban areas and affecting ground stability by example of the city of Irkutsk. The article focuses on the simulation of a 3D-solid model and proves the necessity to consider it under tectonic break determination. The scientific novelty of the introduced 3D-model is in the consideration of azimuths and dips of faults in modeling. The results of the key stages of the modeling method are shown as well as the main difficulties of fault surface connections.
