Abstract
<jats:p>Hulunbuir experiences long, severe winters, with significant wind-chill effects at outdoor ski resorts that pose a high risk of frostbite for children. Traditional indoor ski resorts require substantial investment and high operational energy consumption, making them difficult to promote in less developed high-altitude cold regions. This paper proposes a composite ice and snow venue model combining a compacted snow shell, steel truss load-bearing structure, inner protective layer, and insulated glass zoning, and systematically analyzes its regional adaptability, structural design, and thermal performance. The research demonstrates that the venue, relying on natural cold sources without mechanical refrigeration units, can maintain a stable low-temperature range of -8°C to -5°C indoors (wind speed ≤ 0.2 m/s, temperature fluctuation ≤ ±1°C), eliminating wind-chill effects. The arched load-bearing design and layered compaction ensure snow shell stability, while safety nets and waterproof breathable membranes provide dual protection. Insulated glass zoning achieves the integration of hot beverage service and ice body protection. The venue construction cost is approximately 800–1000 RMB/m², with monthly operating electricity costs of approximately 11,000 RMB, representing a reduction of over 70% compared to traditional indoor ski resorts in both construction (3000–5000 RMB/m²) and operational costs. This model combines structural safety, operational economy, and child-friendliness, providing a feasible technical pathway for ice and snow venue construction in high-altitude cold regions.</jats:p>
