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.

Time graded schemes such as over-current or distance protection schemes are examples of those providing inherent back-up protection; the faulty section is normally isolated discriminatively by the time grading, but if the appropriate relay fails or the circuit breaker fails to trip, the next relay in the grading sequence will complete its operation and trip the associated circuit breaker, thereby interrupting the fault circuit one section further back.

过流保护或距离保护可作为前一种方案的例子，通常采用分时限区别来隔离故障段，如果相应的继电器拒动或断路器拒跳，按时限下一个继电器动作跳开有关的断路器，这样就断开了故障回路的下一段。采用这种方法就获得了完整的后备保护。
