3.3 体量体量构图表现建筑物的轮廓特点,它首要进行体量空间组合,桥梁建筑的体量空间组合属于没有内部空间的类型,它不同于房屋建筑。桥梁建筑的体量空间组合包括桥梁与环境空间和桥梁本身,即以桥面竖曲线为顶界面和河床或沟谷为底界面围合而成的范围内进行实体构造与净空的组合。体量的匀称、纤细以及体量与净空的比例关系对桥梁美有异常重要的意义,尤其是纤细性,如联邦德国桥梁专家费里茨·雷昂哈特(Fvitz·Leonhardt)的论述“在大型桥梁中,纤细性占有举足轻重的地位,它既可减少压在河上的质量,又可增加大胆高翔
3.3 Volumetric body composition The outline of the structure of the performance of the building, which is mainly the combination of volume space, the bridge space and volume of physical combination of buildings belonging to the type of internal space, which is different from the building. The volume and space combination of bridge construction includes the combination of bridge and environmental space and the bridge itself, that is, the combination of physical structure and headroom within a range enclosed by the vertical curve of the bridge deck as the top interface and the river bed or valley as the bottom interface. The symmetry, slenderness, and the proportional relationship between mass and headroom are of paramount importance to the beauty of the bridge, especially slenderness, as discussed by Fvitz Leonhardt, a German federal bridge expert Large bridges, slender occupy a pivotal position, which can reduce the pressure on the river quality, but also increase the bold high
