摘要: 为合理设计填埋场排水层或覆盖层,设计者必须能够估算出各种条件下衬垫上渗滤液的最大水头。本文依据标准Dupuit假设,提出了稳定状态下成层衬垫上最大水头的计算方法。通过与McEnroe(1993)和Qian(2004)的计算结果比较,本文提出的方法是合理的。本文通过参数分析总结了成层介质中不同因素对最大渗滤液水头的影响规律。

Abstract: To design a drainage system for a landfill cover or for a leachate collection systems,the engineer had to estimate the maximum saturated depth over the barrier for any proposed configuration.Based on the Dupuit assumption,numerical solution was presented for steady drainage on a sloping impervious barrier with no flow across the up stream boundary.Compared with the results of McEnroe(1993) and Qian(2004),the present method was shown to be rational.Finally the variation of maximum liquid head in layered drainage media was summarized by use of parameter analysis.
