The influence of the soil stratification on free field traffic-induced vibrations

摘要: This paper deals with the influence of soil stratification on free field vibrations generated by passage a vehicle an uneven road. A two-stage solution procedure is applied for numerical prediction traffic-induced vibrations. First, 2D model used calculation axle loads from longitudinal road profile. Next, response calculated dynamic Betti-Rayleigh reciprocity theorem, using transfer function between and receiver. The road-soil interaction problem solved substructure method. modelled as beam infinite length, while boundary element method, based Green's functions horizontally layered linear elastic halfspace soil. demonstrated example where during traffic plateau are calculated. Three different cases considered layering soil: homogeneous halfspace, layer built in at its base halfspace. Special emphasis goes to It that has considerable both peak particle velocity frequency content
