冻结温度

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。

Thirdly, according to the development of the frozen soil, the coupling model of single freezing pipe of axial symmetry of temperature field, stress field and moisture migration is put forward firstly. Then, by means of the progressing principle of potential field, the coupling model of temperature field, stress field and moisture migration which is under the condition of the multi-freezing pipes is extended. At last, the energy balance equation, stress balance equation, quality balance equation, geometric equation, physical equation, initial and boundary conditions etc are adopted to give the analytic solution to the problem of plane axial symmetry of single freezing pipe.

第三，在对室内试验和现场实测结果研究的基础上，分析了土体冻结过程中温度场、应力场、水分场耦合原理，并按照冻土体形成发展过程，首先建立了单一冷源冻结轴对称温度、应力、水分场耦合模型；接着利用势场的迭加原理，将单一冷源情况的三场耦合问题推广到多冷源情况的三场耦合；最后根据能量守恒平衡方程、应力平衡方程、质量守恒平衡方程、几何方程、物理方程、初始及边界条件，解出了单一冷源平面轴对称问题的解析解。
