桥梁整体顶升技术与工艺研究

Research on the Technique of Whole-slab Lifting in Bridge

目前,相当数量的公路桥梁由于养护罩面等原因,致使建筑限界高度不能满足规范标准要求,严重影响了车辆通行能力,对桥梁安全也构成了潜在的威胁。桥梁整体顶升技术可以在基本不影响桥梁通行与结构安全的条件下,实现对桥梁净高的改善,不失为解决桥梁建筑限界高度不足问题的最佳方案。

For the reasons of maintain covered pavement, many highway bridges lead to the limited height of architecture not meeting the request of criterion standerd, which reduce the ability of vehicle traffic and give potential threaten to bridge safety. The technique of whole-slab lifting in bridge can resolve the above problem to increase the height of bridge under the condition that not affecting the ability of traffic in bridge and structure safety.
