The doctoral thesis by student Hamid Salem Sahar was discussed in the College of Engineering, University of Basra, Department of Civil Engineering, entitled The Effect of Pile Drives in Basra Soil on Neighboring Buildings. The thesis included a study of the vibrations that occur during pile placement operations to determine the safe distance to individual regular structures supported by shallow foundations when energy is transferred from Hammer to the pile Vibrations spread in the soil as a result of the interaction between the soil and the pile, pressure waves are generated at the bottom edge of the pile, shear waves are generated at the surface of the pile, Rayleigh waves are transmitted to the surface of the earth, and additional waves are generated.
In the first part of this research, the effect of vibrations was examined experimentally In different locations in the governorate Basra, specifically: Al-Faw; honorable donkey; Shuaiba; Umm Qasr. Different properties of pile and hammer are adopted.
The vibration response on the Earth's surface is measured via a geophone distributed over a variable distance multiples of the total penetration depth of the substrate. The results showed that pushing the pillars. In soft sediments culture has negligible effects on the shallow foundations of nearby structures. For other pile sections, the safe distance between the driven pile and a typical residential building is about 18 times the smallest dimension of the pile section.
