description The invention discloses a structure-soil interface shear characteristic tester and a shear characteristic acquisition method in the technical field of geotechnical test instruments, and aims to solve the problem that the shear characteristic of a structure-soil interface under the conditions of variable temperature and dynamic shear bearing cannot be acquired in the prior art. The method comprises the following steps: fixing a second direct shear box, displacing a first direct shear box through a sliding part to simulate dynamic shear, simulating a variable temperature working condition through a temperature control device, and measuring interface pore pressure, interface shear stress and sample volume change under variable temperature and dynamic shear through a sensor system; the initial shear stress is used for simulating static shear, and a servo motor is controlled through the shear frequency under the actual working condition to simulate dynamic shear, so that the characteristics of shear strength softe
