Abstract: The columnreinforcing netting composite ground is a soil improvement system consisting of column, reinforcing netting, and surrounding soils. This system has different functional elements, such as, column, cushion, drainage layer, reinforcement and protection. This paper presents and theoretical analysis results as well as the tested columnsoil stress ratio data in the actual projects. The change of stress ratio between the column and the soil with the column spacing, reinforcement netting materials, length of the columns, loading magnitude, column materials and soil properties are carefully studied.
