中文摘要:

基于固体废弃物各种工程性质,提出用土壤水动力学原理来模拟渗滤液的流动规律。建立了以显式格式和有限体积法(FVM)为基础的二维饱和-非饱和渗流模型,并运用于深圳市下坪固体废弃物填埋场内部渗流场的计算。根据计算出的渗流场等值线图,证明模型是合理有效的,有限体积法运用于地下水运动的数值模拟仍然是一种高解析度的数值方法。

英文摘要:

Based on the engineering property of MSW,the theory of soil hydrodynamics was applied to simulate the flow rule of leachate,and two-dimensional saturated-unsaturated seepage numerical model of MSW landfill was developed.This model is applied to Xiaping MSW landfill.The results proved that the model is rational,reliable and effective and the method has theoretic and practical significance in the design of MSW landfill.
