A prediction model of the joint roughness coefficient based on Gaussian process regression

地质科技通报
Objective Estimating the joint roughness coefficient (JRC) is essential for evaluating the mechanical properties of a rock mass. Due to the limitation of a single statistical parameter for characterizing morphology, JRC values estimation by a single ...

Organic Carbon and Texture Control Moisture Dependence of Soil Shortwave Infrared Reflectance

European Journal of Soil Science, Volume 77, Issue 2, March–April 2026.
ABSTRACT Moisture content affects soil reflectance in the optical domain (400–2500 nm), acting as a confounding factor in soil property prediction models. Soil reflectance needs to be simulated efficiently for varying levels of soil moisture, in order to aid soil property prediction efforts and inform physical land surface models.

Experimental Study on Stress Wave Propagation Crossing the Jointed Specimen with Different JRCs

Shock and Vibration, 2021
Most of the rock masses in the outer crust of the Earth are discontinuous. They are divided by joints, faults, fractures, etc. And those discontinuities, generally referred to as joints, greatly affect the property of the rock masses.

Modeling the Spatial Interplay Between Migration and Environmental Conditions

Environmetrics, Volume 37, Issue 1, January 2026.
ABSTRACT The measurement and modeling of migration patterns and potential drivers are often limited by the quality of spatial data at local levels. Our aim is to address these constraints by advantaging of consolidated techniques in geospatial regression and emerging machine‐learning approaches to explore how selected contextual socio‐economic and ...

A new spectral analysis method for determining the joint roughness coefficient of rock joints

, 2019
We propose a new spectral analysis method for accurate JRC determination. To do this, we first propose an average power index Pf to present the amplitude height of a rock joint profile, which considers both the low and high-frequency components of the ...

A Probabilistic Cut Finite Element Method With Random Field Generator and Bayesian Model Calibration for Flow Through Rough Cracks

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 1, Page 298-320, January 2026.
ABSTRACT A new model for the simulation of fluid flow through rough cracks is presented. The model combines a probabilistic cut finite element method (PCutFEM) to capture the unfitted boundary condition at the fluid interface, with a stochastic random field generator to represent the crack asperities.

Joint Roughness Coefficient JRC and Subjectivity in its Determination [PDF]

This bachelor thesis focuses on the Joint Roughness Coefficient (JRC), a key parameter in evaluating the shear strength of rock discontinuities and, consequently, the stability of rock masses. The thesis provides an overview of the development of the JRC

On the Classification of Vehicle Cut‐In Scenarios Severity: Empirical Evidence to Validate the Severity Classification of UN R157

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study validates the Fuzzy Safety Model (FSM) as a tool for classifying the difficulty of vehicle cut‐in scenarios, supporting its role in Automated Lane Keeping Systems (ALKS) safety assessments. Results from a test campaign demonstrate the FSM's effectiveness in categorising preventable cases and its broader applicability in enhancing automated ...
