盐城垃圾填埋场垂直防渗帷幕设计及稳定性计算

Design and stability calculation of vertical anti-seepage curtain in Yancheng landfill

垂直防渗帷幕在城市垃圾填埋场的应用日趋广泛。针对盐城市某固体垃圾填埋场的工程地质条件,设计了相应有效的垂直防渗帷幕工程。根据项目实际工程情况,对若干垂直防渗帷幕技术方案进行比较,选择项目最优技术方案。针对垂直防渗帷幕施工期和库区堆载期的工程稳定性,用FLAC^(3D)模拟计算软件进行相应的计算,对工程施工和后期堆载提供了一定的参考和指导。

Vertical anti-seepage curtain is widely used in municipal landfill.In allusion to the engineering geological condition of landfill site in Yancheng,designed an effective vertical antiseepage curtain project.According to the actual project of the project,compare a number of Vertical anti-seepage curtain technical schemes,select the best technical solution for the project.Aim at Vertical anti-seepage curtain construction period and the engineering stability of the storage period in the reservoir area,used FLAC3 Dto calculate,provided some references and guidance for the construction and post-stacking.
