- 摘要：从环境保护的角度出发,针对灰水溶质运移污染地下水的问题,应用混合防渗材料作为防渗层,通过有限元程序模拟贮灰场的实际运行条件,进行了有无防渗层条件下污染物运移的对比计算分析.结果表明,防渗层可有效地减少灰水渗漏量,缩小污染物的长期扩散范围;在灰场底部和内侧设置防渗层是有效的防污染措施.
- Abstract：Aimed at the problem of ash water solvent transfer polluting ground water, the comparative calculation analysis of pollutant transfer with or without impervious layer is made using the mixture impervious materials as the impervious layer and via the infinite element program simulating the real operation conditions of fly-ash storing sites. The results indicate that the impervious layer can effectively reduce the quantities of ash water infiltration or seepage and shorten the long-term dispersion range of pollutants, and that the impervious layers set up at the bottom and inner sides of fly ash storing site are the effective measure to prevent the pollution.
