| 摘 要： | 多跨连拱桥韵律感强烈,造型优美。该文以软弱地质条件下建造的十一跨钢筋混凝土连拱桥为例,剖析该类多跨连拱桥的结构受力特点及设计思路,提出了采用体外预应力解决墩台拱脚间的不平衡推力的解决方案,并通过设置制动墩将拱桥分联以解决施工期间分次落架的问题。

| Abstract: | The rhythm sense of multi-span continuous arch bridge is strong and its modeling is graceful.The article introduces a 11-span reinforced concrete continuous arch bridge constructed in the weak geology,analyzes the structural stress characteristics and design ideas of this multi-span continuous arch bridge,puts forward the solution scheme to use the external prestressing for solving the imbalance thrust force among the pier,abutment and arch foot,and sets up the braking pier to separate the arch bridge to three unites in order to solve the erection by sections in the construction period. |
