介绍了水泥混凝土路面增设传力杆构建缩缝传荷体系的必要性,提出了推荐的传力杆长度与直径比例、布设间距等;指出可靠、有效的缩缝传荷体系不仅能够改善面层板和基层的受力状态,而且有利于保持路面的整体使用功能、提高路面的使用耐久性。 This paper introduces the necessity of constructing the load transfer system of the dowel joint by adding the dowel bar on the cement concrete pavement and proposes the recommended length and diameter ratio of the dowel bar and the spacing of the laying bar etc. It is pointed out that reliable and effective shrinkage transfer system not only can improve the surface layer Board and grassroots force state, but also help to maintain the overall use of the road function, improve the durability of the road.
