随着高等级公路的建设需要,斜桥和弯桥的应用已日趋普遍,在外荷载作用下以及由于温度变化、混凝土收缩、预加力的施加等原因,将在斜交板梁桥中产生纵、横向位移和转动,这个问题已是当前迫切需要注意的重要细部了,为此介绍下列计算方法以供设计者参考和应用。 With the construction of high-grade highways, the application of inclined bridges and curved bridges has become more and more common. Under the action of external loads and due to temperature changes, shrinkage of concrete and the application of pre-applied force, , Lateral displacement and rotation, this issue is an important detail that needs urgent attention at present. Therefore, the following calculation methods are introduced for designers’ reference and application.
