大型变压器在公路运输中常遇到通过桥梁的难题。假如不清楚桥梁的承载能力,往往选定的运输途径不能获得公路部门许可;或者本来可通过的桥梁却有意避免,而选用其他复杂的方案。因此,在制订变压器运输方案时。按照平板车载重量及尺寸对要通过的桥梁作概略的验算是必要的。公路桥中最常用的是简支梁结构的钢筋混凝土梁式桥,这里,对简支梁桥的验算和
Large transformers often encounter difficulties in passing through bridges in road transport. If the bearing capacity of the bridge is not clear, the transport route chosen is often not allowed by the highway department; or the bridge that could have been passed is intentionally avoided and other complicated options are used. Therefore, when developing a transformer transportation plan. It is necessary to make a rough check on the bridge to be passed according to the weight and size of the flatbed vehicle. The most commonly used road bridge is a reinforced concrete girder bridge with a simple-supported beam structure. Here, the calculation of the simple-supported beam bridge is conducted.
