| 摘 要： | 填埋场粘土衬里可能发生开裂、开孔、解体等形式的破坏。开裂的主要机理是干湿循环作用、物理化学作用及差异沉降作用。开孔的主要机理是管涌和穿透。边坡失稳和冻融循环可能使粘土衬里的连结结构解体。

| Abstract: | Failures such as cracking, penetration and disintegration may occur in the clay liners in landfills.Cracking is mainly due to dry/wet cycling, physicochemical reaction and different settlement. Penetration attributes to piping and perforation. Slope instability and freeze/thaw cycling may lead to disintegration of the clay liners. |
