Technology and Application of Concrete‐Reinforced Saline Soil Subgrades: A Comprehensive Review
The high salt content and pronounced water‐salt migration characteristics of saline soils significantly affect subgrade performance. In recent years, concrete reinforcement has become a prevalent technique for enhancing the stability and durability of saline soil subgrades. This article systematically reviews the state of the art in concrete‐reinforced

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