第五，考虑到实际工程应用，设计并制作了采用增大截面法在拱腹部位加固钢筋混凝土拱圈试件，研究拱腹加固新老混凝土结合面的粘结性能及破坏形式和补强混凝土的施工工艺对新老混凝土结合面粘结性能的影响。

There is much difference between the stress ratio in crown and springe calculated with these two methods. In the crown, most external forces changing into horizontal forces leads to the large decrease of the vertical tension stress. The vertical distribution pattern of the axial forces in the arch and soil pressure is not the same. And near the bottom of the pit the axial tension stress appears. Due to the self-accommodation effect which the external force acts on the arch, the stress in the springe gets lesser too.

拱冠和拱脚处的应力比值跟竖向构件比较相差悬殊；拱冠处由于大部分外力转化为水平拱内轴压力而使得竖向拉应力大大减小；竖向上拱内轴力与土压力的分布模式并不相同，并且在坑底附近出现了轴拉力；拱脚处也由于拱体对外力的自我调节作用而变得比纯竖向构件小的多。
