当公路路线与河流中线斜交时,为了适应路线的顺直,合乎线形要求和行车便利,对于中、小桥梁的修建往往采取斜桥形式。这在设计原则上是完全正确的。某公路建设之初,曾本着这种原则修建了若干座斜桥。但都是砖、石墩台、木桥面的半永久式斜桥。近年来通过养护工程,已逐步分期改建为永久式桥。在改建工程中,本着技术经济合理性的原则,曾就旧有墩台的利用,上部结构形式以及施工方法等几方面作了适当的处理,取得了一些经验。本文拟就这几方面
When the route of the highway is oblique to the middle of the river, in order to adapt to the straightness of the route, it meets the requirements of line shape and traffic convenience. For the construction of medium and small bridges, the construction of inclined bridges usually takes the form of inclined bridges. This is exactly the right design principle. At the beginning of the construction of a highway, a number of inclined bridges have been built on this principle. But they are all brick, stone pier, wooden bridge semi-permanent inclined bridge. In recent years through the conservation project, has been gradually phased into a permanent bridge. In the renovation project, based on the principle of technical and economic rationality, some experiences have been gained in properly handling the use of the existing piers, the superstructure and the construction methods. This article is about these aspects
