摘要
凤岗桥位于三明沙县,跨沙溪河,因其所处的区位及周边环境,景观设计是方案的重点考虑因素。针对凤岗桥景观设计,结合环境需求与使用需求,采用整体结构赋形和单元结构赋形以及二者融合方式分别探讨。整体结构赋型先总后分,优先考虑桥梁整体结构造型,后塑造细部景观效果,设计为双跨连拱桥;单元结构赋型先分后总,选取结构造型模块单元,通过模块设计组合,再根据造型比例调整桥梁整体景观效果,设计为双层板桁结构桥,上层为行车道路,下层为慢行交通。此外,重点考虑经济因素,融合设计现浇预应力混凝土连续梁桥。通过综合比较,推荐采用双层板桁架结构桥型,融入环境又富有地域特色,为后续结构造型设计提供支撑。
Fenggang Bridge is located in Sanming Sha County and crosses the Shaxi River.Because of its location and surrounding environment,landscape design is the key consideration of the scheme.In view of the landscape design of Fenggang Bridge,combined with the environmental needs and use needs,the overall structure shape and the unit structure shape and their integration are discussed respectively.The overall structure is shaped first and then divided,giving priority to the overall structure shape of the bridge,and then shaping the detailed landscape effect.It is designed as a double-span multi-arch bridge;The shape of the unit structure is divided first and then summarized.The structural modeling module unit is selected.Through the module design combination,the overall landscape effect of the bridge is adjusted according to the modeling proportion.The design is a double-deck plate truss structure bridge,with the upper layer for traffic roads and the lower layer for slow traffic.In addition,the economic factors are mainly considered,and the cast-in-place prestressed concrete continuous beam bridge is designed.Through comprehensive comparison,it is recommended to adopt the double-deck truss structure bridge type,which is integrated into the environment and rich in regional characteristics,to provide support for the subsequent structural design.
