연속지지형 매립레일궤도 하부노반에 작용하는 연직토압

Earth pressures caused by tram operations beneath an embedded rail track were estimated using a three-dimensional finite elementmethod. The numerical results were compared with the measured field data to verify the validity of the numerical approach. Both themeasured earth pressures caused by static stationary load and dynamic driving load were reasonably agreed with the numerical resultsadopting static load only. The dish shaped earth pressure distributions with the maximum pressures occurred at the edge of track slabwere found. The tram loads were effectively distributed along the longitudinal track direction up to the distance of 6m. The earthpressure distributions under embedded rail track according to the locations and loading conditions were presented for the reasonablesubgrade design of embedded rail tracks.
