查询词典 frozen soil

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。

Carposina, Navicula caterpillars, flat postornata, soil pests such as mole cricket, can they turn to land the ground froze to death;also bollworm damage, stick insects, sawfly wheat, locust pupae Room nests, etc., to prevent its emergence or incubation in order to better carry out Overwintering insects buried in the 10 ~ 15 cm layer, it should be frozen in the soil before or early spring, while the pests,"sleep" when the Land20 ~ 30 cm, so that exposure of adults or pupae on the ground was frozen to death or birds pecking; such loose soil can also help the soil ripening, and enhance the permeability of soil.

害虫越冬入土在10～15厘米层间，故应在土壤封冻之前或早春，趁害虫"熟睡"之际，将田土深翻20～30厘米，使成虫或蛹暴露在地面上被冻死或被禽鸟啄食；这样也可使土壤疏松，有利于土壤的熟化，增强土壤通透性。

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.
