高山滑雪赛道空间塑形关键技术

Key Technology of Space Shaping of Alpine Skiing Tracks

针对高山滑雪赛道修建中土石方平衡、合理支挡结构选择、符合国际赛事标准形态雪道保证等关键技术问题,通过理论分析和数值模拟等方法,采用调整整体标高和利用开挖土石方填方措施解决了土石方开挖量大难题,针对赛道潜在滑移风险,在D2雪道的填筑过程中现场设置了抗滑桩和抗滑挡墙,保证雪道整体稳定性。

In view of the key technical problems in the construction of alpine skiing tracks,such as earthwork balance,reasonable selection of retaining structure,guarantee of snowway conforming to the international competition standard form,etc.,through theoretical analysis and numerical simulation and other methods,the problem of large excavation volume of earthwork is solved by adjusting the overall elevation and using excavation earthwork filling.In view of the potential slip risk of the tracks,in the filling process of D2 snowway,anti-slide piles and anti-slide retaining walls are set up on site to ensure the overall stability of the snow tracks.
