Model tests are still a popular research tool used to observe and determine the mechanisms of pile-soil interaction. Due to the significant scale effect, the results of model tests performed in the 1g system can only be analysed from the qualitative side. This article describes and presents the results of 1g pile model tests carried out for comparative purposes. There were tested the effectiveness and efficiency of various types of drilling augers forming cast-in-place piles in non-cohesive soil. The SDP and prototype DPDT augers were mainly tested. The tests were performed in fine, moist and fully saturated sand. The screwing resistance of individual drills and Q-s characteristics of pile models were analysed, with its division into the shaft and base resistances. Pile test results were correlated with CPT results. Comparative analyses have shown some advantages and disadvantages of the DPDT auger versus the SDP drill in relation to the screwing torque, load-bearing capacity and settlement characteristic of piles formed by both augers.
