在公路建设中,为了跨越各种障碍物,必须修建各种类型的桥涵,因而桥涵成了陆路交通中极其重要的组成部分。同时,桥梁在经济、国防等方面也具有非常重要的地位。因此,为了保证现有公路的安全畅通,除了要靠精心的设计、严格的施工外,保证对桥梁经常性的养护与维修工作同样十分重要。但目前我们公路部门对桥梁养护工作的重视程度远不及道路,桥梁养护几乎是处于无人问津的状态之中。 In highway construction, various types of bridges and culverts must be constructed in order to cross all kinds of obstacles. As a result, bridges and culverts become an extremely important part of land transportation. At the same time, the bridge also plays a very important role in economy and national defense. Therefore, in order to ensure the safety and smoothness of existing roads, it is equally important to ensure the regular maintenance and repair of the bridges besides careful design and strict construction. However, at present, our highway departments pay far less attention to the bridge maintenance work, and the bridge maintenance is almost in a state of no one’s interest.
