渗透系数的变异性对压实黏土衬垫性能的影响
Effect of permeability coefficient variability on performance of compacted clay liners
摘要
Abstract
Compacted clay liner is the barrier material for landfill; and its thickness and permeability coefficient are important for design. Based on performance design and probabilistic method, the effect of design parameters on contaminant relative concentration and flux at base of liner is analyzed. The variability of permeability coefficient is very significant for the performance of liner. The probability of high concentration (close to 1) at base of liner is large, even the mean concentration is relatively low. This is a big threat to environment, which can't be reflected through deterministic method. From the probabilistic perspective, the requirements of thickness and permeability coefficient for liner are reasonable. Relative to the flux at base of liner, the relative concentration is more sensitive to thickness of liner and should be used as the key indicator for performance evaluation of liner.关键词
