农桥是我国当前的农田基本建设中的重点建筑物之一。随着农业机械化和农村交通运输事业的发展,农桥建设的规模与数量必将与日俱增。据江苏省各地的初步统计,为了搞好农田水利工程的配套工作,除了大量修建跨度5～8米的小农桥外,尚需修建跨度20米以上的农桥10万多座。如何提高设计效率是当前农桥工作中的研究课题之一。
Nong Bridge is one of the key buildings in the current farmland infrastructures in our country. With the development of agricultural mechanization and rural transportation, the size and number of agricultural bridge construction will surely increase day by day. According to preliminary statistics from all parts of Jiangsu Province, in order to do a good job in the supporting work of farmland water conservancy projects, in addition to building a large number of small-scale farmers’ bridges with a span of 5 to 8 meters, over 100,000 agricultural bridges with a span of more than 20 meters need to be constructed. How to improve the design efficiency is one of the research topics in the current bridge work.
