摘　　要：新建蒙西至华中地区铁路煤运通道MHTJ-1标段位于内蒙个自治区鄂尔多斯市乌审旗境内,地处毛乌素沙漠腹地,当地资源匮乏,没有合格的B组填料,通过对周边地区料源地普查、料源分析和工艺性试验结果,最终确定用A组填料掺风积沙改B组填料的物理改良方案,其均能满足重载铁路基床底层的各项指标,为沙漠地区修建铁路在填料选择上提供一定借鉴。The new MHTJ-I section of railway coal transport corridor from Mengxi to Huazhong is located in Wushen Banner, Erdos City, Inner Mongolia Autonomous Region.It is located in the hinterland of the Mu Us Desert.There is scarce local resources and there is no qualified Group B packing.Material source census, material source analysis and technology test results, and ultimately to determine the use of Group A material aerated aerated sediment to B group of physical improvement programs, which are able to meet the heavy railway bed bottom of the indicators for the desert Regional railway construction in the choice of filler to provide some reference.
