摘要：
Soil-bentonite vertical cutoff walls are effective and economical as engineering barriers for geoenvironmental containment. The compressibility and permeability of zeolite-amended soil-bentonite vertical cutoff walls for the purpose of enhancing the chemical compatibility have not been well addressed. These two engineering properties of soil-bentonite backfills before and after amended with zeolite are assessed via a series of oedometer tests. The results are discussed using the generalized state parameter (i. e. e/e(L)) and the void index I-v, which are used to analyze the intrinsic properties of remolded clays.
