| Abstract: | Laying on CWR on manipulable locality of Qinghai-Tibet railway is important to raise the speed of train and reduce the cost of management,it also has important sense to the request of our country railway stride over development. The results of test and analysis on the data of ballast resistance,initial deflection were obtained in Qinghai-Tibet railway. Strength and stability of track were calculated and fastening-down temperature of rail was decided. |
