摘要
针对大跨度钢管砼拱桥在钢管吊装和分段砼泵送的施工过程中，需要通过扣索来保持拱形和分担砼的重量．保证施工质量和安全，控制索力是一种重要手段．通过计算力学的逆分析方法，给出扣索的索力，经算例验证是合理的，其计算程序可作为此类桥型的优化施工软件．
オn process of installation of steel tube and segmental pumpdelivery of concrete for construction of concretefilled steel tubular arch bridge with a long span,bucklecables are required to hold arch shape and to share weight of concrete.In order to ensure quality and safety of construction,an important means to control the bucklecable forces is used.This paper deduces a solution of the bucklecable forces from inverse analysis method of computational mechanics.The method proves to be reasonable through a counting example.The designed computer program has prospect in application for optimal construction of this kind of bridge.
