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.
