The effect of seismic action on stability of saline soil subgrade in cold region based on isothermal stratification method

Earthquake Research Advances
With the change of seasons, the shear strength of saline soil subgrade filler will change with the change of external temperature, which will aggravate the adverse effects of seismic on the subgrade.

Application of FWD and GPR for Performance Evaluation of In‐Service Roads

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Road performance detection typically encompasses structural strength testing and damage assessment, with the resilient modulus serving as a key indicator of structural integrity. To enhance the assessment of road performance, this study explores the combined application of falling weight deflectometer (FWD) and ground penetrating radar (GPR) in ...

Thermal Stability Analysis and Novel Cooling Technology Field Tests for Permafrost Railway Subgrades

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Global warming has intensified the climatic warming and moistening trend on the Qinghai–Tibet Plateau, threatening the thermal stability of railway subgrades in the plateau permafrost regions. However, previous studies have lacked systematic analyses that comprehensively consider the climate along the railway, permafrost conditions, and subgrade ...
