Abstract
This paper will discuss some of the technological developments that have taken place in Japan since the mid-1990s, in the deep mixing method; specifically, the mechanical mixing and highpressure injection mixing methods. Emphasis will be placed on the techniques and methodologies that have developed in response to emergent market and engineering demands, issues associated with the deep mixing method, and the availability of new technology. Unique single and double-axis mechanical mixing machines that are capable of improving ground to form large-diameter columns in the range of 1.6m to 2.5m, are introduced. Also discussed, is a new high-pressure injection mixing system that can stabilize columns having diameters from 2 to 3m, while achieving low waste slurry discharge and low lateral deformations. The use of ICT and a 3D database are reviewed for: positioning construction machines; controlling ground improvement works and displaying the work done in 3D to improve construction efficiency and productivity. Finally, developments and thoughts on the future use of AI is considered.
