The study show that the frozen earth in this area is mainly silty clay. The content of the dissolvable solt is relative high,which is 12.01%, and the main salinity is NaCL and KCL. The research also revealed that frozen intensity would ascend jumpily when the water contend in the soil reached its optimization( 10.61%) and kept rising,and this phenomena got more obvious with the decrease of the temperature. Between 0C and 10C, the frozen intensity vared very obviously, when the temperature is under -10C, the variety of frozen intensity got gently, and the change is not obvious. The frozen strength was influenced by the solution thickness in the soil hole.when the thickness increased, the frozen intensity decreased.
研究表明:那曲河地区冻土区冻土主要为颗粒较细小的粉质粘土:土样易溶盐含量较高,为12.01%,主要盐分为氯化钠NaCL和氯化钾KCL;该地区冻土土内水分达到最优含水率10.61%并继续增大时,冻结强度有个跳跃式的上升,这种现象随着温度的降低而愈明显;由0℃到-10℃时,冻结强度变化十分明显,温度下降到-10℃以后,冻结强度变化趋于平缓,变化不甚明显;冻结强度受土样孔隙中盐溶液浓度的影响,盐溶液浓度增加,冻结强度减小。

They tell me that if the fox would remain in the bosom of the frozen earth he would be safe, or if be would run in a straight line away no foxhound could overtake him; but, having left his pursuers far behind, he stops to rest and listen till they come up, and when he runs he circles round to his old haunts, where the hunters await him.
他们指点我说,如果狐狸躲在冰冻的地下,它一定可以安然无恙,或者,如果它逃跑时是一直线的,没有一只猎犬追得上它;可是,一旦把追逐者远远抛在后面,它便停下来休息,并且倾听着,直到它们又追了上来,等它再奔跑的时候,它兜了一个圈子,回到原来的老窝,猎者却正在那里等着它。

Our country firstly put forward such design principle of Qinghai-Tibet railway engineering as "lower temperature actively, reduce the heat into the subsoil, and assure the heat stability of frozen earth for the quality stability of construction", creatively adopt such corresponding measures of frozen earth construction problem as: for the poor frozen earth developing section, line should avoid as possible;for the geology of ice at high temperature and unstable frozen earth zone, the method of bridge instead of subgrade shall be adopted;in subgradeconstruction, such facilities as heat stick, rubble ventilation subgrade , rubble ventilation berm, ventilation pipe subgrade and laying heat preservation board etc shall be adopted to raise the stability of frozen earth subgrade;during the excavation of bridge, culvert , foundation pit and scouring prevention trough, creatively adopt single-tooth knapper and solve the problem of frozen earth excavation;during the construction of bridge and culvert, durable concrete and three-step maintenance method are adopted to assure the outside and inside beauty of structure.
我国在世界上首次提出"主动降温、减少传入地基土的热量、保证多年冻土的热稳定性,从而保证修筑在上面的工程质量的稳定性"的青藏铁路工程设计原则,创造性地采取了解决冻土施工难题的相应对策:对于不良冻土现象发育地段、线路尽量绕避;对于高温极不稳定冻土区的高含冰量地质,采取"以桥代路"的办法;在路基施工中采用了热棒、片石通风路基、片石通风护道、通风管路基、铺设保温板等多项设施,提高冻土路基的稳定性;在桥涵基坑、挡水埝基槽开挖中,创造性地应用了单齿破碎器,解决了冻土开挖难题;在桥涵工程施工中,采用了耐久性混凝土,采用了三步养生法,保证了结构物内实外美。

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.
