Journal ArticleDOI
The complex phenomenological model for prediction of inhomogeneous deformations of railway ballast layer after tamping works
TL;DR: Sysyn et al. as mentioned in this paper reported ORCID 0000-0001-6893-0018, V.M. Kovalchuk and O.Nabochenko: ORCid 0000-0003-4350-1756, O.
Journal ArticleDOI
Experimental investigation of the dynamic behavior of railway track with sleeper voids
TL;DR: In this article, the authors studied the dynamic behavior of railway track with sleeper voids in the ballast breakdown zone and proposed a practical method of the void parameter quantification for the purpose of track-side and onboard monitoring.
Journal ArticleDOI
Experimental study of railway ballast consolidation inhomogeneity under vibration loading
TL;DR: In this article, a method of ballast local consolidation measurement is proposed based on the velocity of impact wave propagation that is measured with device, and the measurement analysis has shown more than 4 times higher consolidation under the sleeper center than for unconsolidated ballast.
Journal ArticleDOI
Performance study of the inertial monitoring method for railway turnouts
TL;DR: The coefficient of variation of the measured accelerations could be significantly reduced under the consideration of all the possible influencing factors to improve the performance of the inertial measurements systems.
Journal ArticleDOI
Estimation of carrying capacity of metallic corrugated structures of the type Multiplate MP 150 during interaction with backfill soil
TL;DR: In this paper, the stressed state of a railroad structure with a large cross section spanning more than 6 m, which is made from metallic corrugated sheets of the type Multiplate 150, was estimated depending on the residual deformation of vertical diameter of the pipe, the modulus of elasticity of backfill soil, and the degree of compaction.
