تحديد معاملات المرونة باستخدام طرائق القياس السيزمية البئرية (Down Hole)‎ للأغراض الجيوهندسية : دراسة حالة

الملخص EN

Seismic down-hole method was applied to investigate dynamic characteristics of subsurface geological structure for geotechnical proposes, by analyzing recorded first arrivals of P waves and S waves, which was used to determine the seismic velocity (Vp, Vs) up to 30m depth.

The calculated seismic velocities, measured densities in the boreholes and Win_DownHole software was used to obtain the young Modulus, poison ratio, shear modulus, bulk modulus.

Analysis of the results and correlate it with litho-logical situation appear the benefits of used method to represent the elastic characteristics of subsurface structures and insure that the study area is affected by collapses or cavities at various depths of the bore holes.
