INVESTIGATION OF THE STRESS– STRAIN STATE OF DRAINAGE TRAYS OF HIGHWAYS, TAKING INTO ACCOUNT INCOMPLETE CONTACT WITH THE GROUND

Abstract

In this article, a study of the stress -strain state of drainage trays of highways is carried out taking into account incomplete contact with the ground base. The task of calculating drainage trays is reduced to the calculation scheme of an infinite strip supported by ribs on an elastic base, taking into account incomplete contact with the ground base. The Winkler model was chosen as the model of the soil base. The analytical solution was obtained by the method of generalized solutions using integral Fourier porosives. For the numerical implementation of the task, this article has compiled a calculation program in the Delphi environment and the output of graphs is carried out using the AutoCAD system. The article provides a detailed analysis of the results obtained, which are of great importance in conditions of close consideration of the real slave design of drainage trays of highways.
