This study includes Seismic Refraction Tomography (SRT) and Multi-channel Analysis of
Surface Waves (MASW) survey. 12 shallow refraction profiles and 2 profiles for MASW were
conducted in teaching hospital project site in Mosul University to delineate some of shallow soil
engineering characteristics for construction purpose. The linear arrays by using 12 geophones with
10 Hz frequency are used. Both of compressional (P) waves and MASW data were acquired and
interpreted using seismic tomography method and MASW methods to create 1-D shear velocity
model respectively. A number of engineering parameters such as Concentration Index, Material
Index, Density Gradient and Stress Ratio are calculated. The seismic velocity values ,engineering,
consolidation ,and strength parameter show that the site have three layers just as follows: the first
one is the upper layer which corresponds to recent superficial deposits is characterized by an
incompetent rock quality, the second one is the middle one that corresponded mostly to the river
deposits composed especially of River terraces and clays is characterized by fairly competent rock
quality While the third one is the lower layer is corresponded to the upper part of Fat’ha formation
which is mostly composed of marl layers is good competent rock quality .Hence the 3rd layer is
suggested for engineering and foundation purpose.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
