Triaxial Low-Temperature Creep Tests of Artificially Frozen Soil

Abstract:

With the increasing in freezing shaft sinking depth of the mine，Mine permanent derrick was located into the frozen wall. The internal force distribution of the shaft-tower foundation was obtained by field measurement shaft-tower foundation basal pressure, foundation reinforced strain and the strain of concrete and foundation deformation of mechanical quantity. The numerical simulation of the interaction between coal derrick and foundation in freezing and thawing process shows that: the field measurement and numerical simulation laws were consistent and the values were in good agreement. It has very important theoretical and practical significance for the safe production of derrick and future derrick foundation design in freezing method construction.
