Provided is an ice avalanche-type glacial lake outburst surge generation and height measurement device. A glacial lake outburst test device includes a glacial lake simulation module and an ice avalanche surge module. An impact path, an impact angle, an impact scale, an impact velocity and a landslide density of an ice avalanche slider are controlled by simulation means. During formation of ice avalanche surges, the ice avalanche slider rushes into the glacial lake at a high speed, an ice avalanche pushes water to move in a sliding direction, thus forming a first surge, then continues to move to the bottom of the lake under the inertia and discharges a certain amount of water at its back. Movement of the landslide drives surrounding water to converge quickly into the back area, thus forming a second surge. Surge waves evolve around with a water entry point as a center.
