摘要
对桥梁进行加宽,国内外常采用上下行分离式桥梁形式,该结构类型现在成为桥梁运营管理和行车安全控制的难点,分离式桥梁一体化是解决这一问题的较好方法。以分红河桥为例,讨论了铰接和刚接两种连接方式对桥梁性能的影响,并提出了一种新的刚性连接方案,为同类桥梁连接拓宽提供了参考依据。
A common way to widen the bridges is incorporating the separated bridges by uplink and downlink. The running-manage and the safety control of the bridge are nodus of this kind of structural. A good way to resolve this problem is incorporating the bridges. As an example of hong-he Bridge, the effects on the performance of bridges by hinge joint and rigid connection are discussed, also a new type of rigid connection is put forward, which is a reference to bridge incorporate
