摘要
以简支梁为例,介绍了预应力混凝土梁预拱度的设置方法,从施加预应力的控制、混凝土的强度与弹性模量、存梁时间等影响因素阐述了预应力预拱度的控制方法,对预应力桥梁的施工具有重要意义。
Taking simple bracket as an example, the author introduces setting method of pre-stressed concrete beam camber, illustrates its control measures form control of pre-stress, strength of concrete and its elastic modulus, and time of beam storage, which has important meaning for construction of pre-stressed bridge.
