填埋场排水层淤堵条件下渗滤液最高水位研究
Analysis of maximum liquid depth in landfill drainage layers under clogging conditions
摘要
Abstract
Based on the simplified model for estimating the clogging time which was made by Rowe and Fleming, the assumptions and derivations are developed reasonably due to the time-space distribution of clogging in drainage layers; and a simplified model is obtained which can reflect the development of clogging and the variation of hydraulic conductivity of the drainage layers. Using the cell analysis of water balance, a method for calculating maximum liquid depth in drainage layers which is based on the maximum liquid depth clogging model is proposed. Comparing with the steady and transient results, it is shown that no clogging results are in accordance with the transient results, which all tend to the steady results. And the clogging must be considered when clogging is serious which may affect the liquid depth markedly. Parameter analysis shows that the greater previously (the smaller later) the hydraulic conductivity, the longer the drainage distance, the faster the infiltration rate, the higher the concentration, the more serious the impact of clogging on liquid depth. At the same time design suggestions are proposed for improving the drainage system.关键词
