基于剖面特征分析的冬奥会滑雪赛道辅助设计方法

Assistant Design Method of Ski Courses in Winter Olympics Based on Profile Feature Analysis

目的研究冬奥会技巧型滑雪赛道剖面特征,提出量化和可视化辅助设计方法,用于指导滑雪赛道选址、设计及施工。方法基于笔者北京2022年冬奥会筹办工作实践经验,通过建立“赛道基准数字模型”和“赛道特征玫瑰图”,分析冬奥会技巧类雪上赛道剖面特征;将上述分析方法应用于赛道规划阶段的选址过程、设计阶段的校核过程,以及实施阶段的施工纠偏过程。结果通过“赛道特征玫瑰图”可清晰梳理出北京冬奥会技巧类雪上赛道剖面特征;拟合“赛道基准数字模型”和施工现场可得出需要调整的赛道区域。结论结合北京2022年冬奥会筹办工作实践检验,上述方法可用于指导滑雪赛道的选址、设计和施工。

This paper studies the profile features of ski course in Winter Olympic Games,and puts forward a graphic aided design method to guide the location,design and construction.By establishing"Standardized Course Model"and"Profile Wheel Assessment"which applied to the Beijing 2022 Winter Olympic Games′site selection process,the verification in the design stage and the construction correction process in the implementation stage.Through the"Profile Wheel Assessment",which can clearly sort out the profile features.By fitting the"Standardized Course Model"the course area can be obtained.Through practice of Beijing 2022 Olympic Games,the above method can be used to guide the site selection,design and construction of ski course.
