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.

本文以青藏铁路格尔木-拉萨段那曲河地区安多段(DK1561+975～DK1562+530)冻土路基为对象，对该地区冻土的工程性质进行了室内试验研究；对不同含水率、不同压实度的土样，研究在特定温度变化范围内工程性质的变化：初步分析了易溶盐含量对冻结强度的影响：测试了土样的导热系数；在室内土工试验的基础上，根据测试结果和数据，对安多段区域地温场进行了数值模拟，分析了该工点区间内合理片石护道、碎石护坡结构参数，评价了路基稳定性。

Quickly the trickle becomes a flood of glistening linseed oil as the beam sinks earthwards, taut and protesting, its creaks blending with the squeaking and rumbling of the grinding-wheels and the occasional grunts and sighs of the camels.

随着大梁越压越低，缆索越绷越紧，大梁的嘎吱声，石磙的辘辘声，以及骆驼不时发出的咕噜咕噜的呼吸声和叹息声响成一片，榨出的油也很快地由涓滴细流变成了一股晶莹发亮、奔腾不止的洪流。
