Researchers, academics, engineers and professionals are invited to submit original research papers, case studies and technical contributions related to transportation soil engineering and geotechnics in cold regions. Submissions are expected to address frontier theories, innovative methods, field investigations, numerical and experimental studies, construction technologies, maintenance practices, monitoring, safety assessment and intelligent operation of transportation infrastructure in cold regions.

Topics include, but are not limited to:

● Climate change, permafrost degradation and adaptation strategies for cold-region transportation infrastructure.

● Resilient construction and sustainable development of railways, highways, airports, ports and urban transportation systems in cold regions.

● Mechanical, thermal and durability characteristics of embankment fills, frozen soils, improved soils and functional materials.

● Frost heave, thaw settlement, salt expansion, differential deformation and long-term deformation control of roadbeds and embankments.

● Hydro-thermal-mechanical-chemical multi-field coupling models for frozen soils and geotechnical structures.

● Field testing, laboratory testing, in-situ monitoring and full-scale model experiments for cold-region transportation geotechnics.

● Long-term service performance, performance prediction and life-cycle assessment of cold-region transportation infrastructure.

● Dynamic response, fatigue damage, vibration control and soil-structure interaction under traffic loading.

● Geotechnical problems in bridges, culverts, tunnels, underground construction and slopes under complex cold-region conditions.

● Nondestructive testing, remote sensing, structural health monitoring and multi-source data fusion for cold-region infrastructure.

● Artificial intelligence, scientific machine learning, large/foundation models and physics-informed neural networks in cold-region geotechnical engineering.

● Digital twins, smart operation and maintenance, risk warning and decision support for resilient transportation infrastructure.

● Uncertainty quantification, Bayesian methods, reliability analysis and multi-hazard risk assessment under freeze-thaw cycles and extreme climate events.

● Green and low-carbon materials, ecological construction technologies, carbon-footprint evaluation and environment-friendly maintenance in cold regions.

● Engineering standards, design methods, construction organization and operation/maintenance experience for cold-region transportation infrastructure.

● International case studies, cross-regional comparisons and young scholars’ innovative research in cold-region transportation geotechnics.
