摘要
粘土防渗衬层是构成危险废物安全填埋场防渗系统的重点,要求其渗透系数≤1.0×10-7cm/s,厚度不小于0.5 m,对于山谷型安全填埋场来说实施起来具有一定的难度。本文主要从材料、设计、施工三大因素对安全填埋场实施粘土防渗衬层进行探讨。
Clay underlayer is the major component of the antiseepage system of a hazardous waste landfill its infiltration coefficient is required to be lower than or equal to 1.0×10^-7cm/s and its thickness not less than 0.5 m. This is difficult for a valley-type waste landfill to implement. This paper has a discussion on the application of clay underlayer to waste landfill from the aspects of material design and construction.
