Analysis on vibration screening by Rayleigh wave propagation through open and in-filled trench

This research tackles the important problem of ground vibrations brought on by pile driving, machine foundation, blasting load, and train-induced load, as well as their possible effects on adjacent structures and delicate equipments. Numerous investigations using experimental and computational methods have been conducted on vibration isolation. Rayleigh waves are the primary carrier of vibrational energy. The phenomenon of Rayleigh wave propagation through various elastic media, such as an in-filled trench, is highly intriguing, yet there is a dearth of literature on it. It has explored an innovative solution using Geofoam, crumb rubber, a non-biodegradable waste and concrete. This research discusses how the reflected and transmitted Rayleigh wave has altered the displacement before and after the trench. The whole vibration screening investigation was conducted with the transmission, reflection, and propagation of Rayleigh waves in mind. A standard numerical analysis has also been conducted to determine the differences between the two approaches. The displacement of soil particles in both vertical and horizontal directions has been observed. Numerous parametric study variations, such as trench depth, width, location, and operation frequency, have been investigated in this study. There is a favourable result when the finite element and analytical findings are compared.
