Determining the shear strength of rockfill is a key task for the design and stability analysis of
rockfill structures. When direct shear tests are performed, the well‐established ASTM …

Real-time evaluation of the mechanical qualities of ballast beds is essential for improving
tamping effort in railway maintenance. This study aims at evaluating the mechanical …

While various train-borne techniques have been developed for measuring railway track
stiffness, differentiating stiffness at different track layers remains a challenge. This study …

In this paper, an improved nonlinear model of railway ballast is proposed based on the
modified Ludwik model. The accuracy of model-based structural damage detection relies on …

We propose to combine a physics-based finite element (FE) track model and a data-driven
Gaussian process regression (GPR) model to directly infer railpad and ballast stiffness from …

In unidentifiable model updating problems, the posterior probability density function (PDF) of
uncertain model parameters cannot be well approximated by a multivariate Gaussian …

Wind speed forecasting can serve a wide spectrum of purposes, including scheduling of a
power system and dynamic control of structures. A lot of models are widely used to forecast …

Intelligent data-driven monitoring procedures hold enormous potential for ensuring safe
operation and optimal management of railway infrastructure in the face of increasing …

This paper investigates the feasibility and practicability study on the use of Markov chain
Monte Carlo (MCMC)-based Bayesian approach for identifying the cement-emulsified …

The dynamic response of a moving vehicle has been utilized to extract the frequencies of the
supporting bridge. In most previous studies, the vehicle was modeled as a single-degree-of …
