| Abstract: | Engineering geological mapping was carried out at a scale of 1:25000 in the city of Bam, located in southeastern Iran, to provide engineering geological information as a base for seismic microzonation of the city. In this study, Seismic Refraction and Vertical Seismic Profiling (VSP) surveys were employed along with boreholes in order to identify the characteristics of subsurface material in Bam city. A number of different kinds of maps of the city were prepared consisting of Iso-depth, Iso-velocity, and Iso-Poisson's Ratio maps. The study also involves trial pitting and continuous core recovery, in-situ, and laboratory tests. Borehole data, index properties of soils, and standard penetration test results were used to assess subsurface conditions. Geophysical and geotechnical data were combined to simulate geotechnical boreholes and prepare engineering geological maps to provide basic data for seismic geotechnical microzonation to facilitate in the reconstruction of the city of Bam. |
