战时铁路隧道快速抢修技术初探

根据战时铁路隧道不同的破坏形式，重点分析了隧道的破坏机理。针对轻度破坏、中度破坏和严重破坏三种不同程度的破坏设想分别做出了相应的抢修技术初步探讨。其中，着重介绍了清方（改路堑）、加固边墙、补强拱圈、修建临时明洞（棚洞）、暗挖、洞门防护等技术措施，并提出快速抢修的一些其他思路，以期为战时铁路隧道抢修技术和平时病害整治提供参考借鉴。

An Exploration into the Rush-Repairing Techniques for Railway Tunnels in Wartime

According to the different damage forms of railway tunnels in wartime,the analysis of the failure mechanism of the tunnels is focused on in the paper.Different corresponding explorations are made into the corresponding rush-repairing techniques respectively for the three different degrees of damage assumed———mild damage,moderate damage and serious damage. Stress is placed on some useful technical measures of rush-repair,such as the cleaning of earthworks （instead of cutting way）, the reinforcement of side walls,the consolidation of arch rings,the building of the temporary open-cut tunnel（shed tunnel）, tunneling,portal protection,etc.Some other thinking ways for rush-repair are also presented in the paper,which aims at providing some useful reference for rush-repairing techniques for railway tunnels in wartime and for trouble-shooting railway tunnels in peacetime.
