Engineering geological mapping at east of Isfahan city using GIS

Abstract

Quaternary deposits which cover about a half of country area are counted suitable places for building, water security and agriculture. In spite of studying different characteristics of these deposits, the recognition dispute of engineering geological characteristics of these deposits has not found its position yet. To show the distribution and local relationship of different investigated characteristics such as surface and subsurface soil and soil texture and compaction in the area and geotechnical parameters analysis, it has been used to prepare an initial map including geological maps and liquefaction susceptibility zoning map, and at last with summation of investigated characteristics, it has been made an applied engineering geological map for the East of Isfahan. This is a multipurpose, complete and medium - scale map, in which it has been brought the parameters such as subsurface stratigraphy, groundwater depth, liquefaction susceptibility, inflation potential, spread of fill soil, confronting depth to sand layers and a lot of another parameters. The final result of this research is more recognition of engineering geological of Isfahan area, to identify engineering geological hazards and giving the ways to solve these problems.
