000012897 520__ $$2eng$$aThe Tubular Track (TT) railway system is a twin-beam modular railway system consisting of two Reinforced Concrete (RC) beams on which steel rails are continuously supported. The beams are linked with galvanised steel gauge tie bars and continuously supported by soil foundations. The main emphasis of this investigation was to develop and verify static and dynamic analysis methods and mode­ ling techniques which can be used to simulate the TT railway system accurately. The analysis models used range from simple theoretical models based on elastic foundation principles, to two-dimensional beam elements, and ultimately to complex three-dimensional solid finite element models. An insitu reference model with known deflections and design parameters specific to a TT railway section is used to evaluate the accuracy and validity of the different analysis methods. Simplification of a subgrade foundation by simulating a soil stiffness supporting the TT beam is investigated by comparing the Finite Element Analysis (FEA) results of various soil models using the parameters of known soil formations. The sensitivity of the TT system to design parameters is also investigated to indicate which parameters the design is sensitive to and where small variations in these parameters require due consideration for future and analysis of the TT railway system.
