随着我省公路建设事业的发展,我省公路桥涵施工技术,在学习祖国建筑石拱桥丰富经验的基础上,近年又有一些发展。这就是在新建公路上修建了大量的干砌块石涵洞、石拱桥以及石台墩工程等,其中有跨径为5米、8米(拱矢度1/3.5)及10米(拱矢度1/4)的石拱桥共五座,均经1959年常年洪水的考验,证明质量良好。在修建过程中,随着砌作工艺的提高,建成的桥梁逐渐达到整齐美观,拆除拱架后拱圈的沉落值较之用白灰砂浆砌的拱桥,情况反而良好。
With the development of highway construction in our province, the construction technology of bridges and culverts in our province has made some progress in recent years based on the rich experience of studying stone arch bridges of the motherland. This is the construction of a large number of new roads in the dry block stone culverts, stone arch bridge and Shitou Dun works, including a span of 5 meters, 8 meters (arch 1 / 3.5) and 10 meters (arch 1 / 4) A total of five stone arch bridge, both by the 1959 flood test, to prove good quality. During the process of construction, with the improvement of the masonry craft, the bridges built gradually become neat and beautiful. The settlement of the arch ring after the demolition of the arch frame is better than that of the limestone masonry arch bridge.
