Device and method for testing impact of rolling stones on affiliated foundation of power transmission line

The invention discloses a device and a method for testing the impact of rolling stones on an affiliated foundation of a power transmission line. In order to solve the problems that complex mountainousterrains cannot be accurately simulated and different rolling stones cannot be effectively prevented from impacting an iron tower, the device comprises a support, a to-be-tested tower, the rolling stones and a high-speed camera, an inclined sliding surface is arranged on the support, a through groove formed in the longitudinal direction is formed in the sliding surface, and a plurality of small stones are embedded in the inner wall of the through groove; the to-be-tested tower is arranged close to the lowest point of the through groove, a pressure sensor is arranged on the surface, right opposite to the through groove, of the to-be-tested tower, and a displacement sensor is arranged on the surface, back to the through groove, of the to-be-tested tower; the rolling stone can roll down along the through groove and
