基于比例视诱法的高速公路跨线桥梁景观技术研究

Study of Aesthetic Techniques for Highway Flyovers Applying the Scale and Visual Inductiveness Method

高速公路跨线桥梁的结构形式以多跨布置的梁式桥为主,其景观要求也通常只需要考虑立面范围内的整体效果,文中提出了比例视诱法开展高速公路跨线桥梁的景观技术研究,主要包括以黄金分割比与墩高与跨径之比完成桥梁孔跨布置,然后通过完成增加翼板宽度和腹板斜做等方法完成上部结构断面视觉诱导处理,结合韵律感、选型、墩梁过渡等完成桥墩景观设计.在此基础上,以从莞高速跨东深公路处的石马河大桥为具体工程背景,开展景观优化设计研究,取得了良好的景观效果,验证了比例视诱法的有效性与可行性.

Highway flyovers are usually multi-span beam bridges,for which aesthetics mainly concern overall aesthetical effects in their elevations.This paper offers the Scale and Visual Inductiveness Method（SVIM）as an aesthetic technique for highway flyovers.The method includes span arrangement by the gold partition scale and the ratio of span length to pier height,visual inductiveness for cross-section of upper structures with widened flanges and inclined webs,and pier aesthetic design with the consideration of rhythm,shapes and transition between pier and beam.Then the process of aesthetic optimization design is carried out based on the Shima River Bridge located at the interaction of the Congguan Highway and the Dongshen Road,Which has achieved great aesthetical effects and has verified its effectiveness and feasibility of SVIM.
