两港公路大治河桥主桥景观设计

A Landscape Design of the Main Bridge of Dazhi River Bridge on Lianggang Highway

鱼脊连续梁桥是一种截面形式比较特殊的梁桥,由等高梁体与变高鱼脊立墙组成,为下承式的混凝土梁桥。鱼脊立墙作为鱼脊桥梁的主要构件,不但为大跨径桥梁提供了结构刚度,同时也承担着桥梁景观功能。以两港公路大治河桥主桥——国内首座下承式特大型宽桥面混凝土鱼脊连续梁桥为例,介绍其景观设计思路及方案的研究。

Fin back continuous beam bridge is a through concrete beam bridge with special section forms, being composed of equal altitude beam bodies and unequal altitude fin back vertical walls. As the main components, the fin back vertical wall not only provides the structural rigidity for the large span bridge but also presents the bridge landscape features. Taking the main bridge of Dazhi River Bridge on Lianggang Highway, the first through super-large concrete fin back continuous beam bridge with wide deck for example, its landscape design ideas and plans researches are introduced in this paper.
