| Summary: | In vibration screening technique, the effectiveness of in-filled trenches in soil has been extensively studied over the years considering various synthetic in-filled materials. However, the application of natural but cheaper in-filled materials in vibration screening technique is still scarce. The present study investigates the efficiency and aptness of bamboo, a naturally available hollow and less expensive element, as a vibration barrier to mitigate the vibration induced by machine excitation. The vibration screening efficiency of the bamboo in-filled trench has been assessed based on two factors such as amplitude reduction factor (ARF) and system effectiveness (SE). Considering a vertical harmonic load as the source, three-dimensional finite element explicit dynamic analysis in the time domain has been performed assuming the soil as linearly elastic, isotropic, and homogeneous. The effect of various parameters such as the length and depth of the trench, the distance of the trench from the vibration source, the spacing between the bamboos, and the frequency of excitation on ARF and SE has been analyzed. |
