About the temporary load on arched structures made of corrugated metal under a road embankment

Introduction. The issue of features of formation and practical calculation of temporary moving load from vehicles on arched structures made of corrugated metal under the road embankment is considered. These features are related to the scheme of static work and deformation of a relatively flexible structure — mainly to bending under the influence of the prevailing vertical pressure from the soil of the embankment and in the conditions of the transfer of a temporary load through the soil of the embankment, which distributes this load in a certain way. Problem Statement. In the current regulatory and methodological documents regarding the design of bridges and pipes, information on the rules for determining the amount of temporary moving load on pipes under highway embankments is limited to instructions regarding the parameters of a typical scheme of wheel loads (NK-100 or NK-80) and regarding the distribution of properties of the soil of the embankment, without setting out the methods and formulas necessary for practical calculations, which complicates the design to a certain extent. Normative and methodical documents directly related to the design of road structures made of corrugated metal also do not contain sufficiently complete and correct information on this issue.
