In order to study the mechanical properties of frozen soil-concrete contact interface, a kind of dynamic direct shear system for frozen soil was developed. Based on the framework of a static shear apparatus, it was installed with a dynamic loading system and a temperature control module. With this dynamic direct shear system, dynamic shear tests of frozen soil under specified temperatures are able to be operated. Then dynamic parameters of frozen soil are measured. By placing concrete blocks in half of the shear box and frozen soil in the other, we operated a series of dynamic shear tests on the frozen soil-concrete contact interface. The results show some behavioral characteristics of the contact interface under dynamic loads, multi-factor comparison revealed the influencing factors and the variation.
