在西德南部,许多铁路隧道是在十九世纪下半期建成的,已不能满足今天铁路电化对隧道防水和净空的要求。技术改造措施,必须在列车运行的条件下进行,因而产生了特殊的工程技术和运营技术问题。在本文中对此进行论述。
In southern West Germany, many railway tunnels were completed in the second half of the nineteenth century and can no longer meet the requirements of today’s railway electrification for tunnel waterproofing and headroom. Technical transformation measures must be carried out under the conditions of the train operation, thus creating special engineering and operational technical problems. This article discusses this.
