Rationale for Selection of Gear Ratio of Hydromechanical Transmission of Dump Trucks of Extra Heavy Payload Capacity

Механика машин, механизмов и материалов, 2016
The dump trucks of extra heavy payload capacity are dominant transport of modern quarries. Constructions of hydromechanical transmissions and their units are determined almost entirely by the technologies of mining works and nowadays they should comply ...

A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part I Theory

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Pattern formation in geological materials is commonly described using analogies to Turing‐type reaction–diffusion systems, yet a unifying thermodynamic explanation remains elusive. Here we develop a multiscale, thermodynamically consistent framework for pattern‐forming instabilities in porous media undergoing coupled thermo–hydro–mechanical ...

Influence of Asphalt Emulsion Stabilization on Pavement Structural Behavior and Life Cycle Assessment (LCA)

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Assessing pavement sustainability requires jointly evaluating structural performance and environmental impacts, yet these dimensions are often analyzed separately. This study proposes an integrated framework combining mechanistic–empirical pavement design and life cycle assessment (LCA) to quantify the structural–environmental trade‐off associated with

Analysis of Underground Cavern Surrounding Rock Stability and Anchoring Effects Under High Stress Using an Optimized DDARF Method

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study focuses on the stability of surrounding rock (SR) in underground cavities of China’s western high‐stress regions, using the tailwater pressure–regulating chamber of a hydropower station on the lower Jinsha River as the case. Models with and without bolts are established for excavation simulation.

Experimental and Numerical Investigation of Reinforced Soil Slopes With Vertical Rib and Inclined Reinforcement: Application to Embankment Slopes

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Reinforced soil technology is widely applied in slope stabilization, yet the optimal configuration of reinforcement remains a key design challenge. This study presents a comprehensive investigation of vertical rib‐reinforced and inclined‐reinforced geogrid layouts through scaled physical model tests (1:10) and finite element simulations using MIDAS GTS.
