摘要
在特大跨径桥梁方案的比选中悬索桥总是可以作为优选方案,而作为主要的承重构件锚碇结构在总造价中占有较大的比重。所以,对悬索桥锚碇的合理设计及施工方案的优化比选就显得尤为重要。本文对锚碇的设计采取了一种新型结构——岩锚+重力锚复合形式,并且以某悬索桥为工程实例,验证该锚碇设计方案在经济、结构、施工等方面的合理性和优越性。
In the large span bridge scheme comparison, suspension bridges are always can be used as optimal scheme. But anchor block as the main load-bearing elements account for a large proportion in the total cost. For anchor block of suspension bridges, therefore, the rational design and the optimization and comparison of construction scheme is particularly important. In this paper, the design of anchor block has adopted a new type of structure-rock anchor ＋ gravity anchor composite form, and with a sus- pension bridge as an engineering example. Verify that the anchor block design scheme has rationality and superiority in terms of economic, structure, construction and so on.
