Problems solved by technology

However, since the interaction mechanism between the vegetation root system and the clay layer is not yet clear, the relationship between the advantages and disadvantages of the plant root system on the soil properties of the clay cover layer with the characteristic anti-seepage task cannot be quantitatively judged. Therefore, the type of vegetation and the root soil cover layer in the lan

Abstract

The invention relates to an environmental evolution and impermeable failure analog simulation system for a refuse landfill closure coverage system and belongs to the technical field of environmental engineering. The analog simulation system consists of a man-made climate system, a coverage system failure test platform, a digital imaging system, a stress-temperature-moisture monitoring system, a flow and sediment monitoring system and an environment parameter control and acquisition analysis system. The simulation system can be used for realizing environmental evolution and impermeable failure analog simulation of the closure coverage system under external dry-wet alternation and freezing and thawing cycle and internal high-temperature and supernormal environment conditions of the refuse landfill, dynamically monitoring multiple parameters such as the vegetation root growth, crack extension, stress-temperature-moisture distribution and subsurface runoff sediment and infiltration rainwater amount inside the closure coverage system and comprehensively analyzing the multiple parameters through the environment parameter control and acquisition analysis system.

Description

technical field [0001] The invention relates to a similar simulation system for environmental evolution and anti-seepage failure of a landfill closure and covering system, belonging to the field of environmental geotechnical engineering. Background technique [0002] The ecological safety of the anti-seepage system of the garbage sanitary landfill is a priority development area of ​​the national environmental protection "Twelfth Five-Year Plan"! In particular, the failure control of the landfill closure cover system is one of the major engineering problems that need to be solved urgently in the field of environmental protection engineering. my country's "Technical Specifications for Domestic Garbage Sanitary Landfill" (CJJ17-2004) recommends that compacted clay or geosynthetics be used as the closure cover system, that is, the permeability coefficient of the anti-seepage clay layer must be less than 1×10 -7 cm / s . However, most of the existing landfills in my country are ...
