Background technique

With the development of the national economy and the improvement of the level of urbanization, the amount of municipal solid waste is increasing rapidly. There are three main final disposal methods for MSW: sanitary landfill, composting and incineration. Sanitary landfill is the most commonly used waste treatment technology in the world. On the basis of scientific site selection, it adopts necessary site protection and treatment methods and reasonable landfill structure to minimize and eliminate the impact of garbage on the environment, especially on groundwater pollution. In recent years, many cities have successively built large-scale domestic waste landfills.

In urban sanitary landfills, in order to prevent leachate from seeping into the ground and causing groundwater pollution, a liner system must be installed. In the process of landfilling, the garbage is landfilled in layers and blocks. Due to the continuous accumulation and compression of garbage and the action of the landfill operation vehicles, tension will be formed in the cushion layer, and the cushioning system may lose its originality. Some functions, in order to prevent this phenomenon from happening, the anchoring area is generally set at the top of the slope or the platform of the segmented slope.
