Abstract

Firstly, several common vertical anti-seepage forms for modern sanitary landfill are reviewed and compared. According to the unreasonable calculation method of the wall thickness in the New Code, this paper proposes a reasonable calculation method of the wall thickness through the two engineering project cases: valley type and plain type landfill, reflecting on the reasonable choice of the vertical anti-seepage forms. For the valley type landfill where the cover layer has a certain thickness, jet grouting pile and post grouting is 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.
