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.
