Abstract: Building No. 12- Internal Dormitories for Women at Tikrit University are two stories, constructed as bearing wall system. After a period of operation, several aggressive cracks have been found in the superstructure due to excessive foundation settlement. To detect the main causes led to these problems and damaged in this building,a Geophysical and Geotechnical investigation are carried out. The scope of this investigation included a review of the available data pertinent to the building construction and the problems in the foundation that cause aggressive cracks. Conduct a subsurface investigation that consists of drilling, securing representative samples and field Standard Penetration Tests (SPT). Collecting disturbed and undisturbed soil samples for visual examination and for carrying out basic laboratory testing of select soils, including chemical analyses of soil samples. Investigate the cavities and weak zones underneath the foundation of the building and nearby the building using seismic surface survey and cross-hole test, and Perform a geotechnical engineering analysis using the information obtained from the available investigation and laboratory testing.
Keywords: Geotechnical Investigation, Geophysical Investigation, Cross-hole test, Seismic tests, Seismic Refraction test.
