The permeability coefficient, also known as hydraulic conductivity. In isotropic media, it is defined as the unit flow rate under a unit hydraulic gradient, representing the difficulty of the fluid passing through the pore skeleton, expressed as: κ= K ρ G/ η, In the equation, k is the permeability of the porous medium, which is only related to the properties of the solid skeleton, κ Is the permeability coefficient; η Is the dynamic viscosity coefficient; ρ Is the fluid density; G is the acceleration of gravity. In anisotropic media, the permeability coefficient is expressed in tensor form. The larger the permeability coefficient, the stronger the permeability of the rock. Permeability coefficient of strongly permeable coarse sand and gravel layer> 10 meters per day and night; The permeability coefficient of weakly permeable sandy soil is 1-0.01 meters per day and night; Permeability coefficient of impermeable clay< 0.001 meters per day and night. Based on this, it can be seen that the soil permeability coefficient is determined by the soil texture. The testing scope includes waterproof geotextile, anti-seepage geotextile, woven geotextile, composite geotextile, filament geotextile, etc. The testing items include tensile testing, appearance testing, mechanical properties, width deviation, permeability coefficient, antioxidant performance, etc
