Abstract: Frozen soil-structure interface is the weak zone of building foundation, therefore, it is of great significance to study the cyclic shear property of the frozen silt-structure interface. By using the large-scale multi-functional cycle direct shear apparatus for the frozen soil-structure interface, the experimental studies of cyclic shear property of frozen silt-structure interface are carried out. The study results are as follows: (1) in the first cycle, the frozen soil shear zone displays the maximum dilatation at the beginning stage, and this maximum dilatation increases with the increase of initial normal stress when this initial normal stress is more than 500 kPa, and then decreases with the decrease of initial normal stress; (2) on the whole, the normal displacement increases with a cyclic loading time at a decreasing rate, and the peak-to-trough of normal displacement is observed inside each shear cycle; (3) the peak shear stress in each cycle decreases, but the rate of decrease gradually slows down with the cyclic loading time, and the relationship between the two is a hyperbolic curve. Moreover, the maximum shear stress formed under the joint actions of the freezing force and the frictional force between the structure and the frozen soil is observed in the initial stage of the first cycle. This maximum shear stress increases with the increase of initial normal stress.
