摘要
由于曲线本身的特点 ,造成设计施工有很大困难 ,所以当桥梁位于弯道上时 ,尤其是当弯道半径较大 ,桥梁跨径又较小时 ,则大多“以直代弯”地修建成多跨直桥。
Because of the intrinsic characteristics of the curves, it's difficult to design and construct the curved bridge. When the bridge is located in the curve, particularly the radius of the curve is large and the span of the bridge is short, most of this kind of bridges will be built as multi span curve bridge composed of straight girders. This paper analyzes the reliability of the curved bridge composed of straight girders from two aspects: character of geometry and static dynamics.
