铁路改扩建工程中,常涉及一些铁路既有曲线的改造;时常看到整条曲线被废弃,深感痛惜;特别是有些曲线经由桥梁隧道,或是位于高填深堑中,曲线稍有拨改,这些桥隧和高填深堑连同曲线-起被废弃,引起很大的工程量和工程费用,并引起一些技术难题。如何充分利用这些既有曲线和曲线上的构筑物,减少工程量和工程费用?在长期的工程实践中,摸索出了几种办法,和大家一起探讨。
In the course of railway reconstruction and extension, it is often involved in the reconstruction of existing railway curves. It is deeply regretful to see that the entire curve has been discarded. In particular, some curves pass through the bridge tunnels or are located in the high-cut graben with a slight curve As a result, these bridges and tunnels and high-fill graben along with the curves have been abandoned, causing significant engineering costs and construction costs and causing some technical problems. How to make full use of these existing curves and curves on the structure to reduce the amount of engineering and engineering costs? In the long-term engineering practice, worked out several ways to discuss with everyone.
