| 摘 要： | 从分析昆仑山隧道渗漏水地形特征入手，得出沟谷地形是多年冻土隧道渗漏水的原因，重新定义移动边界概念，提出产生移动边界特征的充要条件，为进一步认识多年冻土提供了理论依据。引入移动边界计算模型，分析了计算参数的取值原则，采用有限元技术，利用该模型计算和预测冻土的融化深度，并将计算结果与工程实际进行比较，最后得出昆仑山隧道冻融区的变化规律，为隧道病害治理提供了可靠途径。

| Abstract: | Channel is the reason resulting in water seepage from Kunlun Mountain tunnel by analyzing relationship between location of seepage and terrain. Moving boundary is redefined to rediscovery permafrost; and the essential conditions resulting in moving boundary are presented too. A computational model of moving boundary is introduced to compute thawed depth of permafrost; and how to determine some parameters is discussed. The computational results are compared with the actual ones. The disciplinarian of variation of frozen-thaw range around Kunlun Mountain tunnel is drawn to treat disease of the tunnel finally. |
