Laboratory Investigation of Soil Plugs in Open Ended Model Piles Driven into Sand
Open-ended pipe piles are often used for both land and offshore structure foundation because of their relatively low driving resistance. During driving, soil enters into the open-ended displacement piles, which is known as soil plugging. This paper addresses an experimental study of the plugging effect on the capacity of open-ended piles driven in sandy soil. A series of tests were conducted in the laboratory on small scale model pipe piles installed in sand with different soil conditions. The effect of pile diameter and soil density on plugging behavior of this kind of pile was evaluated. The laboratory test results show that plug length generally increases as pile diameter increases, and the relative density of soil decreases. The jacking force for pile driving was evaluated from the model tests, which significantly depends on the plugged length as well as soil properties. Furthermore, the effect of penetration speed on soil plugging was evaluated. It was found that the length of the soil plug inside the pile became smaller with the increase of pile penetration speed. A correlation between plug length ratio (PLR) and incremental filling ratio (IFR) is proposed based on the laboratory experiments.
