Abstract

In this study, the geologic formations of central part of Karaj alluvium are studied and a new division for layers is presented. The results of hundreds geotechnical in-situ and laboratory tests in Karaj alluvium were carried out and analyzed. Based on soil material properties, the study area is divided to six individual layers. In each layer, the results of a large number of in situ and laboratory test to determine geotechnical properties of soil are classified and analyzed. Finally, average geotechnical parameters for different layers of soil in study area are presented. To determine the range of modulus of elasticity and relation between bearing capacity and SPT number in Karaj alluvium, results of laboratory and in-situ tests were assessed and compared with instrumentation data.
