РАСЧЁТ ТЕПЛО - И ВЛАГООБМЕНА МКЭ В ЗЕМЛЯНОМ ПОЛОТНЕ ЖЕЛЕЗНЫХ И АВТОМОБИЛЬНЫХ ДОРОГ

Abstract

The author describes the procedure to calculate heatand moisture exchange in the earth bed of railroads and automobile roads by the method of finite elements (MFE). He uses differential equations of the theory of heatand mass transfer in capillary and poriferous media. These equations are presented nondimensionally. It allowes to bring thermalphysic transfer coefficients to the symmetric kind. The last allows to obtain basic MFE equations with symmetric coefficients and this is possible to use in the present computing MFE complexes.

Описана методика расчёта тепло и влагообмена в земляном полотне железных и автомобильных дорог методом конечных элементов (МКЭ). Для этого используются дифференциальные уравнения теории теплои массопереноса в капиллярно-пористых средах. Эти уравнения представлены в безразмерном виде, что позволило теплофизические коэффициенты переноса привести к симметричному виду. Последнее обстоятельство позволяет получить основные уравнения МКЭ с симметричными коэффициентами, что можно использовать в существующих вычислительных комплексах МКЭ.
