摘要

隧道围岩冻胀变形机理是寒区隧道工程常见的问题之一。首先评述了国内外现有关于寒区隧道冻胀机理的几种解释，然后对采自西部某寒区岩样进行饱水冻结，通过CT扫描技术观察了岩体内部细观结构变化、水分迁移，发现了围岩冻结后发生收缩的现象，从细观角度研究了岩体的冻胀和收缩机理，完善和补充了围岩冻胀机理假说。

Abstract

As is known to all that the freezing-heaving mechanism of tunnel surrounding rock is a common problem of the tunnel in the cold region. Firstly

the several existent theories about freezing-heaving mechanism are introduced and evaluated. Secondly

the freezing experiment of rock sample is mode; after saturated

the rock samples from a cold region in West China. The CT scanning technology is applied to measure the meso-structure change of rock sample and the water transfer within the sample. The shrinkage phenomenon in volume has been found after the rock sample frozen. Finally

the freezing-heaving mechanism of tunnel surrounding rock is studied

which is believable to be helpful to the tunnel in the cold region.
