EVALUATION OF TENSILE FORCE OF LINER SYSTEM WITH THE VARIATION OF HEIGHT OF INCINERATED ASH

摘要

A liner system is installed on the bottom and the side slope of a waste landfill. Tensile forces can occur due to waste compaction which is transferred into the geosynthetics by friction. The long term design strength of the liner system placed on side slope in landfill may be determined by creep rupture strength, so it is very important to estimate the amount of tensile force created in the liner system, especially on the shoulder of liner system in course of filling. In this research, centrifugal model experiments and FEM analysis were conducted to study the variation of tensile force creating at the shoulder of liner system in course of filling. It is found that the tensile force creating at the shoulder of liner system increases remarkably with increasing height of incinerated ash.
