摘要

基于渗透和弥散作用，探讨了黏土固化注浆帷幕对污染物的阻滞机制，通过土柱试验，分析了注浆帷幕对重金属污染物的渗透性能和弥散性能，采用污染物运移过程数值模拟的一维对流-弥散计算模型，研究了重金属污染物在注浆帷幕中的运移规律。试验表明，不同的污染物质在黏土固化注浆帷幕中的渗透性能和弥散性能不同，镉的迁移速度大于铅。数值计算表明，注浆帷幕的厚度及其渗透性、弥散性和水力梯度等重要控制参数对重金属污染物在帷幕中的运移过程具有显著影响。

Abstract

The permeability and diffusion are employed to analyze the retention mechanisms of clay-solidified grouting （CSG）curtain to contamination in landfill. Its permeability and diffusion capacities of CSG curtain to heavy metal cations are obtained by column test. Using 1D flow and transport model which can take convection and dispersion of wastes into consideration

the contaminants transport process through CSG curtain is evaluated. The test results show that the permeability and the diffusion capacities are different for different heavy metal cations; and transport velocity of cadmium is more quickly than lead. It is found that the most important factors affecting the transport process of heavy metals include the thickness

permeability

diffusion capacities and hydraulic gradient.
