摘要
通过对青藏铁路清水河段站场路基的初步试验,获取了地温变形数据,探讨站场路基的冻结和融化过程的规律.实验表明:站场路基下冻土人为上限发生了上移,多年冻土得到了保护,为类似路段多年冻土工程提供借鉴.
By means of some preliminary experimental study on station subgrade in Qingshuihe Section of Qinghai-Tibet Railway, the deforming data of temperature fields underneath is obtained, the rule of the process of embankment's freezing and thaw is discussed, its action of protecting permafrost is analyzed The experimental results indicate that permafrost can be protected under the condition of enough height of roadbed and insulation protection, at the same time, some lessons for similar permafrost engineering are supplied.
