ABSTRACT
Supplementary methods of analysis for railway track (SMART) has been developed on the basis of knowledge acquired through two decades of laboratory studies, field observations and computational studies on rail tracks conducted at the Centre for Geomechanics and Railway Engineering (CGRE), University of Wollongong. SMART is a computer program written in MATLAB to aid in the analysis and design of rail track substructure. It consists of a comprehensive collection of performance-based methods for the analysis of track formation layers such as ballast, sub-ballast and subgrade. The program enables the user to determine the frequency of track maintenance based on the extent of deformation and drainage. The program can be installed and used on any 32-bit or 64-bit computers with Windows XP and later versions. The module of SMART contains details of how to select suitable geogrids to reinforce the ballast, including the shear behaviour at the ballast–geosynthetic interface.
