摘　　要：首先对现代卫生填埋场几种常见垂直防渗型式进行介绍和比较,针对新规范中防渗墙厚度计算方法存在的问题,提出防渗墙厚度的合理选取,通过山谷型和平原型两个填埋场工程实例反思垂直防渗墙型式的合理选择,对存在一定覆盖层厚度的山谷型填埋场,建议采用旋喷桩加桩底后注浆型式进行防渗,对粉土或砂性土地基的平原型填埋场建议采用水泥搅拌桩进行防渗。Firstly several common vertical anti-seepage forms for modern landfill are reviewed and compared,According to the calculation method of the wall thickness which is unreasonable in the new code,it is proposed the reasonable calculation method of the wall thickness. Through the two engineering examples: valley type and plain type landfill,rethinking the reasonable choice of the vertical anti-seepage forms,for the valley type landfill which has a certain thickness of the cover layer,jet grouting pile and post grouting are proposed for the anti-seepage,for the plain type landfill whose foundation is composed of clay or sandy soil,the cement mixing pile is proposed for the anti-seepage.
