Coal mining and washing is accompanied by the production of large amounts of coal
gangue, which exerts a notable influence on the natural environment. However, as a form of …

The effect of water must be considered during the different phases of the life cycle of
infrastructures. When it is not properly managed, it can generate problems that may lead to …

The present study investigates the possibility of using random forest (RF) algorithm for
prediction of hydraulic conductivity of coarse-sized granular material. Meanwhile, the …

Vertical stiffness and shear strength of ballasts are significantly degraded when
contaminated with sands. There is a lack of solutions/studies related to strengthening ballast …

To facilitate rapid, accurate, and convenient detection of ballast fouling, this paper proposes
simplified computational models based on thermodynamic principles to analyze the surface …

The hydromechanical behavior of compacted bentonite in near-field salinity groundwater
environment is of great importance for achieving the low-permeability sealing capacity in …

In this study, a series of cyclic triaxial tests were conducted to study the accumulated strain of
coarse-grained soil reinforced with geogrids, and the effect of the number of geogrid layers …

This paper analyzed the pore structure, quantified the pore fractal dimension, calculated the
grading index (GI) of mixed aggregate, and studied the relationship among GI, pore …

The ballast bed serves as the foundation of the ballasted track, and its performance is
maintained through periodic ballast cleaning. Early detection of fouled ballast bed …

Ballast fouling is a key contributor to the instability of ballasted railway tracks due to its
detrimental influence on the permeability of the ballast layer. Predicting the track drainage …
