Railroad Track Structural Analysis Method for Work Planning: Development andExample Application

摘要

This report documents the developments of a railroad track structural analysismethod, describes an example application, and includes an executable computer program on diskette. This method was originally developed for the Railroad Engineered Management System (RAILER). The method is intended to help provide an estimate of an existing track's suitability to handle its expected loading and to permit an assessment of the potential effects of changes int he track--either improvements or deterioration. It employs five equations that provide values for rail bending stress, tie bending stress, reaction force, ballast surface stress, and subgrade surface stress. The equations are designed for conventional track and will handle the full range of track conditions and loads normally encountered. (kr)
