| 摘 要： | 预应力混凝土曲线箱梁桥始终处于弯扭耦合作用的状况下，扭矩过大时会使曲线箱梁桥产生内侧支座脱空、梁体外移、翻转、裂缝和崩脱等病害，严重影响曲线箱梁桥的正常运行。通过调节支座布置型式，可以使曲线箱梁中的扭矩分布合理，具有一定的现实意义。

| Abstract: | The pre-stressed concrete curved box girder bridge is always in the function of bendingtorsion and too much torsion makes it produce bearing empty, roof of girder bridge move, turn, crack and take off, as well as making it run in abnormality. Adjusting the forms of bearing can make torsion distribute rationally and have some practical meaning. |
