深中通道5×110m连续钢-混结合梁桥设计研究
|
摘要
针对深中通道泄洪区约6.0km非通航桥梁的选型问题,贯彻全寿命周期成本设计理念,采用对比分析法,确定了经济跨径和结构方案,并从梁高、断面形式及剪力键布置3方面优化了结构方案。经综合比选,推荐采用5×110m、高5.0m单箱双室连续钢-混结合梁方案。
For the selection of structure type of no-navigable bridge with length of about 6.0 km located in flood discharge area in Shenzhen-Zhongshan link,the whole life cycle cost design concept was adopted.By using comparative analys is method,the 110 meconomical span length and the steel-concrete composite beam structural scheme were determined,and the structural scheme was optimized by three aspects of beam height,section and shear stud connectors arrangement.By comprehensive comparing,the preliminary design of 5×110 mcontinuous steel-concrete composite beam with single box double compartment sectionand height of 5.0 m was recommended.
