Abstract

One of the primary challenges confronting the quarrying industry pertains to the ground vibrations resulting from the blasting activities in cement quarries, as these vibrations have the potential to inflict significant damage upon adjacent structures. Within the context of this scholarly article, an examination is conducted on a residential edifice situated in the 15th of May city in Cairo, Egypt, which has been impacted by the proximate mining blasting. The ground velocity at the foundation of this residential building is assessed, mainly from the peak particle’s velocity prospective. Subsequently, a finite element model (FEM) of the building is formulated and refined through the utilization of measurements pertaining to ambient vibrations thereby enabling an accurate representation of the building’s actual behavior. Investigation of the building seismic performance was conducted according to Egyptian code of loads through building FEM model. Subsequently, the mitigation of the dynamic consequences arising from ground vibrations resulting from mining blasting is checked through the implementation and comparison of both open trench and retrofitting techniques.
