This method shows engineers the unevenness of the electrical resistivity of the ground improvement body, which indicates imperfections in the mixing process or inconsistency of the compound within the ground improvement body. The monitoring is intended to perform real-time two-dimensional cross-section observation of the ground improvement body. The experiment yielded results enabling engineers to observethe mixing condition of the cement–soil mixture within the ground improvement body by monitoring the level of unevenness of the electrical resistivity of the body, and provides a very accurate quality control process. Quality assurance using wet grab sampling was performed and a uniaxial compressive strength test was conducted and the experimental results showed that the compressive strength of the ground improvement cement–soil mixture at any curing age could be predicted. The quality control and quality assurance method introduced in this research could minimizeuncertain judgments in the current methods.</p><p>&nbsp;</p> ER -
