A Numerical Study of Propagation of Ground Vibrations Caused by Dynamic Compaction by Falling Weight.
لمحة عن المقال باللغة الأجنبية:
This research contains a numerical study using FEM of propagation of ground vibrations induced by dynamic compaction by falling weight. So, we proposed a suitable numerical model which depends on the simulation of both compaction force and prorogation site by using ABAQUS. The calculated results are compared with in-situ measurements obtained from the study of references and a good agreement is showed. The model is tested on a typical example for studying the prorogation and damping of vibrations which enabled us to determine dominant waves and attenuation relation. Finally, a parametric study for the affected factors (falling weight and height, elastic modulus, damping ratio, etc.) is achieved. The obtained results allow evaluating the amplitude of vibrations at some distance to estimate the probable effects on people and adjacent structures to be avoided.
