套轨技术在非洲米轨改造工程中的运用

Application of Mix-gauge Track Technology in Meter Gauge Transformation Project in Africa

非洲铁路基础设施陈旧落后,既有米轨铁路逐步升级改造为标准轨距铁路的需求日益迫切。套轨铁路作为一种过渡形式的铁路,既能实现不同轨距列车共线运营功能,满足不断增长客货运输需求,又能节约土地和建设资金,减少环境污染。在既有米轨铁路不中断运营情况下,进行标准轨-米轨套轨形式的铁路改造也是非洲铁路在过渡阶段的必然选择,本文对其中涉及的主要技术标准和关键技术进行论述。

African railway infrastructure is old and backward,the demand for upgrading the existing meter gauge railway to standard gauge railway is increasingly urgent.As a transitional form of railway,the mix-gauge track railway can not only realize the function of common line operation for different gauge trains,meet the growing demand of passenger and freight transport,but also save land resources and construction funds and reduce environmental pollution.Under the condition that the existing meter gauge railway does not interrupt the operation,the transformation of standard gauge mix-meter gauge railway is also the inevitable choice of African railway in the transition stage.This paper introduced,the involved morms and key technologies.
