Geotechnical mapping investigation of a developing urban area (Nigde, Turkey)

Definitions of urban geotechnical environments are usually required to provide infor-mation about an engineering basis for planners and design engineers in order to pre-pare a rational land use planning and developing urban areas. Therefore, a engine¬e¬ring geotechnical mapping method can be a beneficial way for defining the urban geo-technical environments as visually. In this thesis, Engineering Geotechnical Map¬ping Method (EGMM) was used for Niğde city (in Turkey) so as to investigate and present the geotechnical data that were collected from 45 unpublished reports, mostly extracted from geotechnical investigation reports. The main indispensable parameters for geotechnical design engineers such as lithology and topography of the area, water table depth, bearing capacity of the soils, liquefaction of the soils and some critical geotechnical parameters were noted for the preparation of the geotechnical maps. The Geographically Information System (GIS) was used in order to rearrange and con¬trol all this information, and also to prepare engineering geotechnical maps.
