随着社会经济的飞速发展,公路交通承载的任务越来越重,对道路的质量和外观要求也越来越高,因此公路的改进和扩建工作时有发生。改建工作中遇到最多的问题就是公路加宽带来的新旧道路的拼接问题。在新老路基在结合的过程中,由于实践和各种因素的限制和差异,在结合过程会出现一些大大小小的问题,因此新老路基的对接工作是一项非常重要和非常值得研究的问题。
With the rapid development of society and economy, the tasks carried by road traffic are getting heavier and heavier, and the quality and appearance of roads are also getting higher and higher. Therefore, highway improvement and expansion work have occurred from time to time. The problem most often encountered in the reconstruction work is the splicing problem of old and new roads brought by widening roads. In the process of combining new and old embankment, due to the limitation and difference of practice and various factors, there will be some big and small problems in the integration process. Therefore, the docking work of new and old embankment is a very important and very worthwhile study problem.
