结合国外垃圾填埋场覆盖系统受损的若干案例,分析了屏障型覆盖系统发生渗漏、滑坡、沉陷、侵蚀的各种机制,分析了在覆盖系统的设计和施工中如何避免这些问题,以保证垃圾填埋场的正常运行。
Combined with some failure cases of cover systems at foreign landfills,the mechanisms that induce percolation,landslide,settlement and erosion of barrier cover system are analyzed,and how to avoid these failures in the design and construction of the cover system is discussed to ensure the normal operation of landfills.
