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. 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 Fatha formation which is mostly composed of marl layers is good competent rock quality.Hence the 3rd layer is suggested for engineering and foundation purpose.

Abstract: This study includes Seismic Refraction Tomography (SRT) and Multi- channel Analysis of Surface Waves (MASW) surve y. MASW were conducted in teaching hospital project site in Mosul U niversity to delineate some of shallow soi l engineering characteristics for construction purpose. The linear arrays by using 12 geophones with 10 Hz f requency are used. Both o f compressional (P) waves and MASW d ata were acquired and interpreted using seismic tomography method an d MASW m ethods to create 1- D shear velocity model respectively. A number of engineering parameters such as Conc entration Index, Material Index, Density Gradient and Stress Ratio are calculated. T he seismic velocity values,engineering, consolidation,and strength parameter show that the site have three layers just as f ollows: the first one is the upper layer which corres ponds to recent superficial deposits is charac terized 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 i s the lower layer is corresponded to the upper part of Fatha f ormation which is mostly composed of marl lay ers is good competent rock quality.Hence the 3rd layer is suggested for engineering and foundation pu rpose. Keywords: Refraction Tomography, MASW, geotechnical investigation, engineering parameter. Introduction: Seismic Refraction surveying is a geophysical method traditionally used in many types of exploration programs. The initial application of these surveys was mapping of salt domes in the early days of oil exploration. This method is now routinely used in foundation studies, civil engineering projects and siting studies, engineering environmental, geotechnical investigations, groundwater, dam safety a nalyses, and tunnel alignment studi es 1 -4. Also it is popular and extensively used for imaging the subsurface structure. It is appealing because of its cost effectiveness field operation and easy data interpretation 5.
