Dynamic Response of Elevated High-Speed Railway

The study of the dynamic response of the elevated railway for the high-speed train in the Taiwan area at the preliminary design stage is presented. Two types of the elevated reinforced concrete railway, they being the simple-span and the three-equal-span box girders supported on piers; three types of the high-speed train, namely, the French T.G.V., the German I.C.E., and the Japanese S.K.S.; and the maximum operation speed 350 km∕h are under investigation. The general dynamic stiffness matrix of a damped Timoshenko beam is employed for the structural analysis. The influence line of any dynamic response (also called the dynamic influence line) of the elevated railway subjected to the high-speed train, considered as a series of the moving loads, is calculated by the mode-superposition method. A preliminary design of the section of the railway is proposed for this study.

Full-Scale Field Failure Tests of Railway Bridge

Full-scale ultimate load tests were conducted in March 1995 on the bearings of the Strawberry Park Bridge, a two-span, 45 m (148 ft) long ballasted railway bridge typical of many such bridges around the country. The bridge, located in Los Angeles, was scheduled for removal in spring 1995, a fact which allowed for the performance of failure push tests on the bridge, with the pushing loads applied at the bridge abutments. The main objective of this experiment was to identify the extent to which the rails, ties, and ballast and the plate containing the ballast (ballast pan or tie plate) help to strengthen the bridge during a seismic event. The rails, ballast, and ballast pan were completely removed at one end, while the other end was left in its as-built condition. The bridge was then pushed laterally to failure at both ends. Comparison between the failure loads at each end indicated that the as-built end was 45% stronger than the free end.     

Dynamic Analysis of Metallic Arch Railway Bridge

This work describes some of the most interesting aspects of the experimental and numerical dynamic analyses of the Luiz I Bridge, an old arch double-deck iron bridge, when subjected to the moving loads of the new light metro of Porto. Presented are the methodology and computational tools developed, as well as some of the most significant results obtained from numerical simulations conducted on the basis of an experimentally calibrated finite-element model, both in terms of structural safety and of the comfort of pedestrians and train passengers.     

Model Testing of Two-Layer Railway Track Ballast

Railway track ballast requires regular attention to maintain line and level. A recently developed maintenance method, known as pneumatic ballast injection (PBI) or stoneblowing, re-levels and realigns the track by lifting the sleepers and track and blowing smaller size gravel between the ballast and the base of the sleeper. This creates a two-layer ballast bed. Series of large-scale model tests have been carried out to gain a better understanding of the behavior of such a bed under repeated loading. The results confirm that stoneblowing is a better form of track maintenance than the commonly used ballast tamping method, but the size and type of stone and the thickness of the injected layer are of critical importance in determining the postmaintenance behavior.     

Corrosion Behaviour of New Railway Axle Steels

Corrosion behaviour of two newly developed axle steels (MS3 and MS6) is critically analysed and compared with that of the conventional railway axle steel with respect to the rust formed on the surface and microstructure of the steels. The microstructure of all three steels is ferrite–pearlite. Immersion, salt-fog exposure and dynamic polarisation tests in 3.5 wt% NaCl solution are carried out. New steels have much better mechanical properties and comparable corrosion resistance in immersion and dynamic polarisation test and much better corrosion resistance in salt-fog exposure test than that of the conventional axle steel.
