Abstract：Research purposes：Combined with the design and construction of the slope of No.1 National Highway of the Republic of Congo, this paper introduces the slope protection styles and the concepts and practices for slope ecological protection in the developed countries and offers the measures for dealing with disease appeared in excavation of the slope for the purpose of providing the reference to the similar design and construction.
Research conclusions：The slope ecological protection is an important part of engineering, and protection works should follow the concept of "respecting nature and restoring natural". The style of slope ecological protection should reasonably arrange and suit the local conditions, such as the climate, hydrology, topography, soil quality and sources of material, etc. The slope ecological protection should be coordinated with the surrounding environment to maintain the balance of the ecological environment and beautify the environment.
