Hydraulic durability of geosynthetic clay liners in steep slope sealing systems for landfills constructed in former quarries

在原采石场建造的垃圾填埋场的陡坡密封系统中土工合成粘土衬垫的水力耐久性。旧采石场越来越多地被用来建造堆填区。建造这种垃圾填埋场的工程挑战包括为通常陡峭的采石场壁开发适当的衬砌系统。使用gcl作为衬管系统的一部分是一种可行且具有成本效益的解决方案。然而，在这种特殊情况下，这种解决方案的缺点是缺乏有意义的水力耐久性数据。该提案提出了一种新颖的方法来研究在陡峭边采石场通常遇到的操作条件下的耐久性。预计这项工作将有利于国家和国际一级的废物遏制工作。

Hydraulic durability of geosynthetic clay liners in steep slope sealing systems for landfills constructed in former quarries. Old quarries are increasingly used for the construction of landfills. The engineering challenge in constructing such landfills includes developing an appropriate lining system for the often steep sided quarry walls. The use of GCLs as part of the lining system can be a viable and a cost effective solution. However, this solution suffers from the lack of meaningful data on their hydraulic durability in this particular situation. This proposal presents an original approach to investigate this durability under operating conditions typically encountered in steep sided quarries. This work is expected to provide benefits to waste containment efforts at national and international level.
