斜船台辊轴滑道的设计与施工

斜船台滑道下水工艺,一般采用油脂滑道,近年国内广泛采用钢珠滑道,国外已有辊轴滑道的工程实例。文中结合工程实例,简要介绍斜船台辊轴滑道设计与施工的有关内容。

2000—2002赛季FIS空中技巧比赛场地变化的研究

对2000-2002赛季国际雪联主办的14次自由式滑雪世界大赛空中技巧比赛场地规格变化进行了研究。指出跳台高度和跳台角度是影响比赛成败的敏感指标。二周台、三周台明显增高及角度明显增大,是近年来世界大赛场地规格变化的主要特点,应积极掌握国际大赛场地规格变化基本趋势,加强适应各种规格场地的训练,做到有备无患。

Study on the Water Surge Height Line of Landslide Surge of Linear River course Reservoir Based on FLOW-3D

The occurrence and transmission attenuation of surge is always a problem that researchers pay much attention to. The influence of the first wave height of landslide surge and the following transmission attenuation of surge are involved with many factors, which are mainly： landslide water entry angle, river course depth, river course geometrical properties and landslide mass and material, etc.. This thesis is mainly a research on the properties and transmission attenuation rules of landslide surge which is caused by linear narrow river course. Numerical value simulation will be applied in this thesis to discuss about the features and rules of the occurrence and transmission of surge in different landslide water entry angles and under different influences.
