江苏某填埋场截水帷幕渗流分析

Analysis of a Landfill Seepage around the Water Cutoff Curtain in Jiangsu

可靠的截水帷幕可有效阻断填埋场发生渗漏事故时污染物扩散的途径,对于填埋场的安全性有着重要的意义。通过江苏某填埋场垂直防渗系统中截水帷幕的深度变化,对截水帷幕2侧地下水渗流场进行模拟分析,得出截水帷幕深度需达到20 m,才可保证截流效果。

Reliable water cutoff curtain can enhance the safety of landfill through blocking the diffusion of pollutants effectively while landfill leaking accident happening. Simulation analysis of groundwater seepage flow field at different depths was conducted on both sides of the water cutoff curtain in a landfill of Jiangsu. It can be concluded that the closure effect could be insured by extending the depth of water cutoff curtain to 20 m at least.
