EXPERIMENTAL MONITORING OF SECTIONS OF VARIABLE STIFFNES
Abstract
Growing attention to the development of highspeed railways has accentuated some technical problems. Particularly one can witness changing attitude towards some special track constructions which are sections of variable stiffness. The article describes the results of experiments conducted by the department of track and track facilities of Moscow State University of Railway Engineering in the zone of interfacing of subgrade and artificial structures. The authors proceed with simulation of high-speed train motion at the interface sections, studying dynamic features and operation conditions. They suggest measures of amelioration of structures, taking into account the reducing of stiffness of the track on bridge abutments and raising of the stiffness at the approaches to other structures, in order to reduce the loading of the subgrade and track.
