GCL (bentonite waterproof blanket) is a new type of anti-seepage after the compacted clay liner (CCL), geomembrane (HDPE GM) composite geotextile material. Compared with the compacted clay liner, GCL superiority mainly small thickness, light weight, simple construction, and has a strong self-healing capabilities; compared with other geotechnical materials, GCL flexible anti-differential settlement ability, aging reaction does not occur in the use of simple construction. Different stress, the permeability of the GCL is a different the percolation solution and defect state landfill seepage key. Scientists GCL performance research in the leachate under do a lot of work, but not very well studied, it is difficult for domestic landfill liner system designed to provide comprehensive, scientific theory. Adsorption of different types and number of pollutants, GCL performance occurs which changes its nature changed whether it can continue to meet the requirements of a stable and impermeable security defect state solution percolation, GCL permeability The study was not thorough enough. GCL and CCL impervious more qualitative, the lack of quantitative analysis. These are research Sanitary Landfill must be concerned about and to solve the problem. In this paper, laboratory experiments, theoretical analysis, GCL permeability factors, the self-healing capacity of the leachate under GCL, GCL and CCL impervious comparison carried out a detailed study, simultaneous the hydration swelling test and liquid plastic limit test, then study the expansion properties of the GCL, the relationship between the liquid and plastic limit their penetration coefficient: (1) Reference and learn from the experience at home and abroad, to test the permeability of the GCL leachate pollutants type The amount of pollutants, the order of hydration, the overlying pressure (confining pressure) GCL permeability coefficient. Expansion properties of the GCL bentonite, liquid and plastic limit test to study the expansion properties of the GCL, the relationship between the liquid and plastic limit their penetration coefficient, and a detailed analysis of the impact mechanism. (2) the use of a flexible wall permeameter test the GCL go to the gas tap water, the solution under permeability defect state, turn on GCL self-healing ability, and a brief analysis of the impact of the the GCL self-healing capacity factors. (3) the use of penetration instrument QY1-2-type clay permeability characteristics of a penetration test, under different stress levels adsorption of the the different pollutants CCL impervious performance, from the two aspects of the permeability and the amount of contaminant transport GCL and CCL impermeable performance bioequivalence evaluation.
