跨线桥作为高等级公路上的重要人造景观,应力求造型美观、结构新颖、形式多样,景观设计越来越受到人们的重视,但高等级公路跨线桥的设计需要考虑的因素很多,桥梁设计应从单纯结构或单桥设计的观点中解脱出来,增强桥梁自身的系统性,重视各座桥梁间的有机联系,树立系列桥梁的设计理念。根据盐通高速公路支线上跨桥设计的经验和实际效果的总结,提出系列化设计理念,意在抛砖引玉。
As an important man-made landscape on high-grade highways, flyover should strive to be beautiful in appearance, novel in structure and diverse in form. Landscape design is paid more and more attention by people. However, there are many factors that need to be considered in design of high-grade highway flyover. The design should be freed from the standpoint of simple structure or single bridge design to enhance the systematicness of the bridge itself, attach importance to the organic connection between all bridges and establish a series of bridge design concepts. Based on the experience and actual results of the design of the bridge across the Yantong Expressway, a series of design concepts are proposed, which are intended to attract more people.
