Modelling of Ground Borne Vibration Induced by Road Transport

Abstract

Ground-borne vibrations induced by road transport is common source of environmental problem for residents living near roads where large flow of vehicles is. Any irregular unevenness of road surface increase the transport induced ground borne vibrations. The ground-borne vibrations travel through soil, different types of soil have different properties and transmission loss of vibrations is different. In this paper the spread of ground borne vibration is modelled using numerical modelling and represented using Surfer software. In this research is considered most common soil types in Lithuania: Peat, clay, sandy loam and loam. Calculated soil particle acceleration near vibration source was highest in Clay soil (34,3 mm/s2). The calculations show that in peat soil vibration travel further than in other soils.
