摘要
在中、小跨径拱桥设计中 ,悬链线被较多地作为拱轴线 ,但目前确定拱轴系数的常规方法有其不足之处。荷载法用于拱桥设计中拱轴系数的确定 ,可弥补常规方法的不足 。
Catenary is usually used as arch axis in design of medium and small span length arched bridges.However,the present conventional calculation method for arch axis coefficient m has some shortage. Load method can cover the shortage of conventional method when it is applied in designing arch axis coefficient m.Therefore,load method can increase calculation efficiency and precision,and have reference and application value in design of arched bridges.
