STRESSES IN THE RAILS, THE BALLAST AND IN THE FORMATION RESULTING FROM TRAFFIC LOADS. STRESSES IN THE BALLAST AND IN THE FORMATION (RESULTS OF THE THIRD PHASE: MEASUREMENTS UNDER DYNAMIC CONDITIONS

This report describes the measurement of stresses in a railway track foundation for various speeds and axle loads. It is shown that the stresses acting at: a) the sleeper soffit to ballast interface; b) the ballast to blanket interface; c) the blanket to formation interface are principally dependent upon: 1) the rail to sleeper reaction; 2) the sleeper support (packing) condition; 3) for b) and c) the depth below the sleeper soffit of the two interfaces. Over the speed range studied (o-96 km/h) there were no speed effects other than those influencing the rail to sleeper reaction.
