预应力混凝土结构已被逐渐广泛地应用于工程中,而预压力所产生的拱度正好可以抵消荷载作用下梁板所产生的挠度,显然这对结构是有利的。然而如果拱度过大,对于桥梁工程来说,造成公路桥梁路面不平顺,导致行车不顺畅,产生负面效果。因此,如何控制好结构的拱度也是一个亟待解决的问题。 Prestressed concrete structures have been widely used in engineering, and the camber produced by pre-pressure can just offset the deflection caused by the beams under load. Obviously, this is beneficial to the structure. However, if the crown is too large, for the bridge project, resulting in road and bridge road surface is not smooth, resulting in traffic is not smooth, have a negative effect. Therefore, how to control the structure’s camber is also an urgent problem to be solved.
