| 摘 要： | 2004年,铁道部决定建设遂渝铁路无碴轨道试验段,系统试验研究无碴轨道结构、轨道电气特性、扣件系统、路桥线下工程、100m长定尺钢轨铺设、无碴轨道施工及长期测试等关键技术,通过成区段铺设无碴轨道并进行实车试验,取得无碴轨道工程成套技术和科学数据。遂渝铁路无碴轨道试验段有目的地设计了CRST-I型平板式、框架型板式、纵连板式轨道和CRST-II型双块式无碴轨道等多种类型。试验段于2007年1月进行了实车试验,动车组试验最高速度232km/h,货物列车最高试验速度141km/h。这标志着我国铁路具有自主知识产权的无碴轨道试验段建设成功,并为我国客运专线无碴轨道技术再创新打下了基础。

| Abstract: | In 2004,MOR decided to construct the experimental section of ballastless track of Suining-Chongqing Railway;study,through systematical experiments,the structure of ballastless track,the electric characteristics of the track,fastener system,substructure engineering of bridge,100-m long length-fixed rail laying,key technologies for construction on ballastless track and long-term tests;obtain a whole set of ballastless track engineering technologies and data by sectional ballastless track laying and train experiment.In January 2007,train experiment was carried through on the experimental section;the highest experimental speed of multiple units is 232 km/h,and that of freight train is 141 km/h. |
