CONSIDERATIONS ON TRACK STABILITY IN THE VERTICAL PLANE

CONSIDERAZIONI SULLA STABILITA DEL BINARIO NEL PIANO VERTICALE

Coordinating and integrating the results of Corini (1926), Mischenko (1936) and Martinet (1938) recently (1974) reproduced by Kerr, a re-proposal is made for an analysis of the stability of long-welded rail with regard to its elevation, arriving at the critical load and the length of the track involved in the crisis. After tabling these dimensions for the U.I.C. 60 track, with wooden and reinforced pre-stressed concrete sleepers, a mathematical model is discussed from which indications are derived permitting determination of the degree of safety of the track by means of direct tests.
