摘要：

Economical and environmental viewpoints have recently become very important factors in the construction of soil structures. Floating type deep mixing soil stabilization has an advantage for reducing the construction cost of the soil structure on deep soft soil layers. So it is important to elucidate a mechanism of consolidation settlement of the improved ground with floating columns. In this paper, in order to investigate influenced factor related to settlement of the improved ground, FEM analysis using Cam-clay model as the constitutive equation was initially conducted in the plane strain conditions. Secondly settlement model by the homogenization method in consideration of stress distribution ratio is proposed. Finally loading model tests in the plane strain condition were conducted to simulate the consolidation deformation of the improved ground. In these test conditions it is also confirmed that the settlement of improved portion can be estimated by this proposed model
