In this thesis, the engineering property of the frozen earth in the frozen railway roadbed in Anduo section (between DK1561+975-DK1562+530) of Naquhe region of Qinghai-Tibet railway was studied indoor. The change of engineering property of the earth samples with different water content , density and temperature were researched. The influence of concentration of the diffluent salt to the frozen strength was pilot studied. The thermal conductivity of the soil was experimented. With the result and data of the tests, the earth temperature field in Anduo section was demonstrated by numerical analysis, the structure parameter of the spall revetmentd and the rubble berm was given, the stability of the railway roadbed was evaluated.
