特种荷载过桥的加固措施

Strengthening of Bridges for Special Loads to Pass Through

变压器等特种荷载过桥引起的桥梁结构加固时有发生。以实际工程为例,结合工程现状及特种荷载的相关资料,通过结构计算,提出加固方案,并详细介绍了其施工工艺,以及特种荷载过桥时的注意事项和管理措施。实践证明,该加固措施是卓有成效的,这为超限运输的桥梁加固提供了经验,具有重要的现实意义。

The bridges occasionally have to be strengthened before special loads, such as a large and heavy transformer, pass through. By way of an actual bridge example,and with reference to the specific conditions of the bridge and the related data in connection with the special loads thereof, and through structural calculations,the construction scheme for the bridge strengthening is formulated and the strengthening construction procedures, matters of attention and management steps for special loads passing through the bridge are described in details. Practice proves that the scheme and management steps in the paper work effectively, which provides experiences for strengthening of bridges to be used beyond their design load limit, and is of certain significance of guidance.
