摘要:
提出一种用于解决圆柱形岩石巷道轴对称问题和确定其周围瞬时温度场的数学模型和算法，该方法的显著特征是在岩巷内沿与大气的接触面上引入空气热边界层。通过计算位于俄罗斯远东多年冻土区某实际岩体的融化深度，对该算法及模型进行了验证。研究结果表明：该方法计算所得岩层融化深度取决于隧道衬砌外侧的隔热层厚度，同时还给出了双侧开挖施工后沿隧道长度方向上岩体融化深度的计算结果。
Abstract:
A mathematical model and algorithm for solving axisymmetric problems associated with determining the transient thermal field around a cylindrical stonedrift were described. A distinctive feature of the proposed model was introducing an air thermal boundary layer at the contact with the inner boundary of stonedrift in the formulation of the problem. The algorithm for this model was tested by calculating the thawing depth in a rock massif located in permafrost zone in the Far Eastern Part of Russia. The results show that these calculations yielded the thawing depth, which depends upon the thickness of heat insulating layer outside the tunnel lining. The article also presents the results for calculating the thawing depth for a rock mass along the tunnel’s length when both sides of the tunnel are excavated.
