<jats:title>Abstract</jats:title><jats:p>Deep vibro compaction (vibroflotation) is a soil improvement technique, which was patented by the company Keller in the 1930s and since then it has been continually developed and has been successfully used worldwide for deep compaction of granular soils. The methods for quality control of the compaction works are largely empirical in nature and therefore often unreliable. In a current research project, fundamental experimental investigations on real‐time quality control for the deep vibro compaction were executed. Large‐scale test measurements and numerical simulations were performed to investigate the three‐dimensional vibrator movement during the compaction process. Reliable measurements with measuring instruments on the vibrator tube during the compaction process have been conducted within the current large‐scale field tests. This paper presents the layout of the large‐scale in‐situ tests, moreover, selected test results are shown, and possible indicators of the changing soil conditions are discussed.</jats:p>
