Deep vibro compaction (vibroflotation) is a method, which was patented by Keller in the 1930s and since then it 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 are executed. Large scale test measurements were performed to investigate the three-dimensional vibrator movement during the compaction process. Within the current large-scale field tests reliable measurements on the vibrator tube during the compaction process have been conducted for the first time worldwide. This paper presents selected results of the large-scale tests; moreover, possible indicators for the changing soil conditions are discussed.
