摘　　要：高速公路大修过程中,一般均采用加铺路面结构层的方案,路基一般加铺几层,有的加铺厚度甚至达到了30cm多,而桥面一般只能加铺一层上面层,致使路基路面与桥梁桥面存在一定的高程差,所以桥梁一般进行桥梁整体顶升,以接顺路面。论文介绍了桥梁整体顶升主要控制方法和控制的关键措施等。In the thorough repairation o/highway, the overlay of pavement structure will be used usually. The roadbed generallywiU be added a few layers, the thickness of which sometimes reaches to thirty centimetres. Bridge tend only to overlay a layer above, resulting in a difference of elevatio between the pavement and bridge deck. So the bridge should be overalllifted in order to pick up along the road. The article will discuss the main control method in the overall lifting construction o fbr/dge and its key measures.
