Abstract: With the development of underground space in Shanghai, the ground freezing method is more and more widely used in tunnel construction. In order to avoid the problems of geological disaster which may happen in the freezing construction, it is necessary to do more researches on the physico-mechanical characters of Shanghai soft soil under freezing and thawing action. The characters of three kinds of soils from a certain project in different states (original state, freeze-thaw state, secondary freeze-thaw), are stadied; and the change rules of soil characters under secondary freeze-thaw action are educed. The results will be beneficial to the safety of the tunnel construction.

Key words: freezing method, secondary freeze-thaw, frozen soil, uniaxial compressive strength
