摘　　要：在寒区岩土工程中,岩体中含有一定量的水,冻结后,水冰相变体积膨胀,产生巨大的冻胀力,岩体成为水、冰、岩、气的多相损伤介质.这种不均匀的冻胀力对岩体工程稳定性产生重要影响.运用弹性理论分析了软岩冻结后的冻胀力大小.In the cold geotechnical engineering, when the rock containing a mount of water was frozen, the inner water swells, and the freezing swollen force is emerged, in turn the rock became a damage material containing water, ice, air, rock, et al. The freezing force and deformation have an important role in the stability of rock engineering. On the basis of some assumptions, the elastic theory is used to analyzed the freezing swollen force when soft rock tunnel is frozen in this paper.
