混凝土面板坝趾板体型设计

Design on toe slab shape of concrete face rockfill dam

根据库克建议的趾板体型设计新思想,结合水布垭面板堆石坝趾板结构的具体设计,对趾板体型设计相关的"Y"线的定位、标准剖面体型参数的确定、趾板坐标的计算等进行了阐述。提出了运用向量法建立空间局部坐标系与整体坐标系的转换关系,从而使趾板坐标计算简捷方便,且易于设计修改。对计算方法和坐标转换关系作了详细介绍,可直接运用于类似工程设计,从而使设计工作量大为减少。

According to new idea on toe slab shape design suggested by Kuke and in combination with the toe slab shape design of Shuibuya concrete face rockfill dam, the “Y” line positioning, the shape parameter determination of standard profile, the coordinate calculation related to toe slab shape are presented in this paper. It is suggested that transformation relation between spatial local coordinate system and integral coordinate system be established by vector method, which simplifies coordinate calculation of toe slab and is easy for design modification. This paper presents calculation method and coordinate transformation relation in detail, which can be used in similar project design directly and reduce design work greatly.
