USING ARTIFICIAL BEDROCK IN MINIMIZING THE EFFECTS OF VIBRATION INDUCED BY HIGH SPEED TRAINS ON THE NEARBY STRUCTURES IN ALLUVIAL SOILS

Abstract

An artificial bedrock as wave impeding barrier can be used in practical civil engineering applications as isolation measures to protect structures from strong vibrations transmitted through soft ground nearby high-speed railway track. This study focuses on mitigation of the effects of high speed trains inducued vibrations on the strucutres which are located near the track lines by installing wave impeding barriers. Extensive parametric studies on the screening performance of wave impeding barrier have been done for both active and passive isolation cases.
