Abstract:

Ground vibrations can be caused by various sources such as traffic, construction activities, and industrial machinery. These vibrations can propagate through the ground and into adjacent structures or the environment. Predicting and controlling ground vibrations are essential in various fields, such as transportation, construction, and industrial activities. Regulations and guidelines have been developed in many countries to manage the impact of ground vibrations on people and structures. Open and In-filled trenches are practiced as barriers for mitigating ground vibrations in engineering practices. Coir latex wave barriers are highly sustainable barrier that combines the natural strength of coir fibers with the durability and weather-resistant properties of natural latex. The vibration isolation performance of in-filled trenches using Coir Latex composite was evaluated through laboratory model studies. The study assessed the impact of various factors, such as the trench geometry, latex content, and composite material properties, on the in-filled trenches' isolation performance. The composite with an equal latex and coir fiber content ratio demonstrated over 75% wave isolation efficiency, indicating its effectiveness as a vibration isolation solution.

Keywords:
