近些年来,在我国一度被忽视了的桥梁美学,又重新为广大桥梁建设者所重视,这是一个可喜的进步。工程师们巧妙地利用地形,紧密地结合周围的环境气氛,设计和建造了不少型式优美的桥梁。这些桥梁对改善公路景观,美化城市环境,起了重要作用。桥梁造型美与不美,是根据人们的视觉效果来评价的。而视觉效果的好坏,又与人们的审美观点和视线方向紧密相关,这是人所共知的。一些桥梁建筑的成功之作,正是设计者把握了上述要领而获得的。但也有一些桥梁,特别是立交桥,静止观看还是相当优美的,而在运动状态下观看,则桥型显得杂乱或给人以压抑感。之所以如此,是因为设计者忽视了桥梁的动态视觉效果。
In recent years, the bridge aesthetics, once neglected in our country, has been renewed by the majority of bridge builders. This is a gratifying progress. Engineers skillfully use the terrain, closely integrated with the surrounding environment, design and construction of many beautiful bridges. These bridges play an important role in improving the road landscape and beautifying the urban environment. Bridge modeling beauty and not beautiful, is based on people’s visual evaluation. The visual effect is good or bad, but also with people’s aesthetic point of view and sight are closely related, it is well known. The success of some bridges and buildings, designers have mastered the above essentials and obtained. However, there are also some bridges, especially overpasses, which are still beautifully viewed at rest, while the bridge is cluttered or repressed when viewed in motion. This is so because designers ignore the dynamic visual effects of the bridge.
