Summary: The management of railway tracks is crucial for ensuring railway safety. However, traditional methods of maintaining regional railway tracks are becoming challenging due to financial constraints and lack of manpower. Therefore, a track condition diagnostic system has been developed, using onboard sensing devices installed on in-service vehicles to monitor track conditions through measurement of car-body vibration. Long-term measurements and evaluations have been conducted, demonstrating the effectiveness of the system in identifying degraded track sections and confirming the maintenance effect. Additionally, a method for improving train position and evaluating track condition using time-frequency analysis has been proposed.

Summary: The study analyzed the variation of rock-joint morphology characteristics under different sampling intervals and window sizes using the progressive coverage method and five morphology parameters. The results showed that larger sampling windows generally led to more stable values of the morphology parameters, while R-p, theta(max)*/(C+1)(2D) and M were more sensitive to the sampling spacing effect under small sampling intervals. The study also discussed the interaction between the sampling interval effect and the sampling size effect, as well as the correlation between joint roughness and the sensitivity of the morphology parameters.

Summary: In the Loess Plateau region, loess is commonly used as a filling material for dams. This study focuses on the shear performance of loess filler in dams, as it can affect the overall strength of loess dams. The experiments explore the shear failure characteristics of the filler under different conditions, such as water content, confining pressure, and dry density. The findings reveal that remolded loess is prone to shear expansion failure under certain conditions, and the failure process of a loess dam is influenced by water level and pressure.
