The vehicle impact on the corrugated steel shell in soil-steel structures

Abstract

The paper presents the results of soil-steel structures tests under road and rail vehicles loads, which change their position alongthe track. Quasi static loads are considered in both stepping and continuous measurement method (with minimum travel speed). The impact of dynamic loads from vehicles as a function of vehicle speed was analyzed. Heavy, low-speed driving rides and as a separate group the passage of passenger trains in high speed journeys were con-si-dered. In this cases numerical simulations are performed using com-plex models of soil-steel structures. The specificity (difference) of dynamic effects from dynamic loads of rolling stock on soil-steel structures in relation to classic steel bridges is specified in the paper. The present-ed results from tests shows the favorable interaction of the railway tracks and substructures with the corrugated steel shell in the backfi lling as in the railway embankments.
