| Research Abstract |
In order to clarify the influences of changes of salt and oxidation-reduction environment on quality control of deep mixing method and ground environment, the influences of same changes on the ground environment and geotechnical properties of marine clay layer, underground water quality, flow direction, flow rate and groundwater flow in marine clay layer and aquiclude, the influences of same changes on the development and degradation of hydration reaction products in the improved column, and the influences of same changes on the ground environment of improved column and surrounding ground were investigated.
In this study, the results of overturning the established theory that setting of improved column will influence its surrounding ground and the increased concern of impacts on the ground environment with the increase of improvement materials were obtained. The finding may bring a new policy on the concept of investigation, design and construction of deep mixing method in the future.
