Ground-borne vibration generated by high-speed train viaduct systems in soft-upper/hard-lower rock strata

Abstract

An experimental study and theoretical analysis were carried out to explore the ground-borne vibration generated by elevated high-speed railway in rock strata. Taking a typical rail line constructed on rock area in China as the research object, a set of field tests was performed on Rizhao-Lankao High-Speed Railway, the bridge and ground vibrations were measured as trains passed at 330–340 km/h, then the transferring law and spatial distribution under individual frequencies were investigated. The experiment results indicate that the bridge frequency spectrum exhibited relatively high-frequency vibration peaks caused by short-wavelength irregularity; ground vibration farther than 30 m away can be amplified with a higher frequency and numerous components. Furthermore, the wave propagation equation of a stratified rock strata was established based on direct-stiffness method to explore the vibration attenuation rules via frequency-domain analysis. It is found that the rock area has a weaker correlation between vibration transmissibility and frequency, thicker and harder rock strata loss their vibration attenuation capacity. It can be concluded that the high-speed railways induced vibration on rock strata shows a wide frequency band and large amplitude, the design of reducing vibration aimed at specific frequency is important according to next more detailed numerical study.
