摘要
通过有限元法对隧道衬砌内外表面和衬砌背后冻胀性围岩冻胀产生的应力进行计算,对修建在高寒地区冻胀性围岩中的隧道在冰冻作用下,其衬砌可能造成破坏的原因进行分析,为寒区隧道的抗防冻措施提供理论依据。
In this paper,Finite-Element Method is applied to calculate the stress toward inner and outer surfaces of tunnel lining and frost heave of the surrounding rock behind the lining and to analyze causes of the damage made to the lining by the frost heaving surrounding rock under the condition of ice and frost during the construction of tunnels in cold districts in order to provide theoritical foundation for the frost resistance measures.
