Abstract

Aiming at the problem that the influence of dynamic compaction foundation treatment on pile foundations and the safe construction distance in the wharf land area are mostly dependent on experience and difficult to accurately predict, this paper takes a large deep-water high-piled wharf project in Peru, South America as the engineering background. Focusing on the demand for dynamic compaction treatment of backfilled foundation with mountain-excavated gravel soil in the rear land area, field dynamic compaction tests were carried out. The vibration responses and displacement variations of soil and steel pipe piles at different distances were mainly monitored, the vibration propagation law and the influence of soil compactness on vibration transmission were analyzed, and the influence degree of dynamic compaction on pile foundations was quantified. The results show that the bank slope and water area of the high-piled wharf form a natural vibration isolation trench. The pile vibration velocity induced by low-energy dynamic compaction beyond 15 m is within the allowable range of relevant codes. The vibration amplitude at the pile top is significantly lower than that of soil at the same distance, and low-energy dynamic compaction has a slight influence on pile displacement, which meets the engineering requirements.
