| 摘 要： | 冻胀压力的量值和分布不仅取决于围岩的性态和气象条件 ,而且同衬砌结构的材料、刚度以及施工质量密切相关 ,是一个十分复杂的问题。本文从岩石和土层两种围岩中衬砌承受冻胀压力的机理出发 ,探讨计算方法。通过计算分析 ,对寒冷地区隧道衬砌的设计和施工提出了若干建议。

| Abstract: | Some measures amy be used to provide frost protection for tunnel constructed in severe cold regions.Drainage systems for preventing groundwater accumulating and thermal insulated panels are often used.Even though,in most cases frost heave force acting on tunnel lining still appears obviously.It usually causes lining deformed,cracked and broken.On base of tracing on mechanism and characteristics of frost heave force,different models for calculating it in case of rock and soil surrounding ground are adopted respectively. |
