随着我国科技水平的快速发展,路桥工程建设项目已经迈入了一个施工规模大、技术含量高以及框架结构复杂的阶段,各相关行业虽然对路桥系统的结构设计进行加强,但对路桥过渡段的施工技术、防控措施以及病害处理等方面的研究有所缺乏。在实际路桥工程施工中,路桥与桥台刚度有一定差异存在,路基沉降等情况都会导致桥梁引道位置有不均匀沉降产生,使路面的平整度得到大大降低,同时容易有桥头跳车问题出现。
With the rapid development of science and technology in our country, the road and bridge engineering construction project has entered a stage with large construction scale, high technical content and complicated frame structure. Although the related industries strengthen the structural design of the road and bridge system, Lack of research on construction technology, prevention and control measures and disease treatment. In the actual road and bridge construction, there is a certain difference between the stiffness of the bridge and the abutment. Subgrade settlement and other conditions will lead to uneven settlement of the approach road, which will greatly reduce the roughness of the road surface and easily lead to the problem of bridge jumping .
