高烈度地震区桥型方案比选

Comparison and Selection of Bridge Type Scheme in High-intensity Earthquake Area

以潮州市外环大桥新建项目为背景,对于类似高烈度地震区、城市景观性要求高的桥梁从抗震适应性、景观角度提出了三个桥型方案,并从技术难度及可行性、施工工期、后期养护维修及经济性等多方面进行综合比选,最终确定技术可行、经济合理的方案予以推荐,可为类似桥梁借鉴。

Taking the new project of Outer Ring Bridge in Chaozhou City as the background,the article puts forward three bridge type schemes for the high urban landscape requirement of bridges in the high-intensity earthquake area from the anti-seismic adaptability and landscape angle,comprehensive compares and selects the scheme from aspects of technical difficulties,feasibility,construction period,later maintenance and economy,and finally determines the technical feasible and economic reasonable scheme for recommendation,which can be referred for the similar bridges.
