For reservoir bank slopes around reservoirs in water conservancy and hydropower engineering, most of existing reservoir bank slopes use concrete and stone to protect the slopes, water is easy to accumulate in the slopes, no drainage structure exists, and accumulated water in the slopes is inconvenient to drain. Along with the increase of the running time of the reservoir, the protective layer on the surface of the side slope is easy to move and even fall off, and under the influence of factors such as heavy rainfall, the side slope collapse can be finally caused, so that a certain potential safety hazard exists in engineering.
