| Abstract | ||
| The current study conducted a seismic refraction survey using seismic refraction tomography (SRT), and the use of the multi-channel analysis technique of surface waves (MASW) at the site of Al-Amal apartments in Kirkuk Governorate ( northern Iraq) in order to determine the thickness, depth and velocity of the sub-surface layers. Moreover, a geotechnical assessment is measured in addition to determining the characteristics of these layers and specifying the appropriate layer for establishing the project.The data are processed and interpreted by using SeisImager™/SW software to obtain the velocity of longitudinal waves (VP) represented in the form of a seismic tomography section. The velocity of shear waves (VS ) is extracted from the phase velocity of Rayleigh surface waves using MASW method. The 2D seismic tomography sections represent longitudinal velocity (VP) and the depth of the survey lines. It also has been got three one-dimensional sections representing shear waves (VS ) with the depth. The results show the presence of three layers, and through dynamic flexibility parameters are calculated, and two of geotechnical parameters are applied for the three layers based on the seismic velocity of longitudinal, shear and density. According to these geotechnical parameters, the third layer has better geotechnical specifications than the layers above it, which is suitable for the engineering project. . | ||
