Abstract: Because the offshore pile installation has great risks, it is very important to do accurately analysis and do statistical analysis before and after pile installation. A pile foundation installation database was established based on previous pile driving data. In order to effectively utilize the existing pile foundation installation data in the database, a recommendation method for offshore pile driving cases was formed using similarity algorithms and twin network technology. The results show that the similarity algorithm can be used to recommend the cases that are most consistent with the construction site before pile driving. Twin network can help researchers identify the most similar pile driving cases. The research results could be helpful for engineers and researchers.
