摘　　要：双曲拱桥在上世纪60年代至80年代应用广泛,但是由于其存在整体性差,有水平推力,荷载等级低,通航空间小等问题,现已较少采用,已建的双曲拱桥也在逐步拆除。该文通过对苏州市新郭桥的拆除方案进行研究,对此种桥型拆除过程中可能发生的问题进行了探讨,并给出了解决方法。同时对其他可行的拆除方法也进行了介绍。The double-curve arch bridge was widely used from the 1960s to the 1980s,but it has been less used now because of its poor integration,low horizontal thrust and load,small shipping space and etc.In result,the built double-curve arch bridge is demolished step by step.The article studies the demolishing scheme of Suzhou Xinguo Bridge,discusses the problems possibly caused in demolishing this kind of bridge,gives the solving method,and also introduces the other feasible demolishing methods.
