Transfer of Heat, Moisture in Seasonally Freezing Ground of Roadbeds (O Perenose Tepla i Vlagi v Sesonnopromerzayushchikh Gruntakh Zemlyanogo Polotna Avtomobilnykh Dorog).

摘要

In this article a method is furnished for solving differential equations in partial derivatives. The method describes in a unidimensional task the process of heat and moisture exchange taking place in roadbeds and road surfaces. The solution was obtained using a digital application of conversion. Using an 'Nairi-S' electronic computer, the method makes it possible to determine the winter redistribution of moisture in the ground of roadbeds and also the amount of heaving. The results of the specific computations carried out agrees rather well with the test results.
