Abstract
According to the problem of design theory laging behind engineering application, with the thickness increasing of deep alluvium for the freezing shaft-sinking engineering, the frozen wall is regarded as homogeneous and isotropic thick wall cylinder while designing and calculating, and the calculate results based on the elastic ' and elastic-plastic theory can't apply to the freezing shaft-sinking engineering in the future. In this paper, frozen wall thickness design theory of the present research situation and the existing problems were summarized. The radial creep displacement of heterogeneous frozen wall will reduce 25 % ~ 30 % when the homogeneous frozen wall, so the bearing capacity and deformation performance of frozen wall can befully used and the thickness of frozen wall can be reduced efficiently.关键词
