随着我国经济的快速发展,公路建设也在如火如荼的进行中。然而,公路的功能越来越赶不上现代交通发展的步伐,双向四车道逐步加宽到双向八车道,并有进一步加宽拼接的趋势,对原有高速公路的升级改造势在必行。本文通过对施工中的加宽设计和具体施工方式方法进行的系统研究,并对新老路堤的沉降变形以及新路堤地基处理方法进行了研究,结合笔者多年参与公路建设及扩建的经验进行阐述,希望能为项目施工提供借鉴。
With the rapid economic development in our country, highway construction is in full swing. However, the function of the highway is less and less able to catch up with the pace of the development of modern transportation. The two-way four-lane road is gradually widened to the two-way eight-lane with the tendency of further splicing. It is imperative to upgrade and upgrade the existing expressway. In this paper, systematic research on widening design and concrete construction methods in construction is carried out. The settlement and deformation of new and old embankments and foundation treatment of new embankments are studied. Based on the author’s experience in road construction and expansion for many years, Hope to provide reference for the construction of the project.
