Measurement and prediction of the initial settlement of cube-type artificial reefs caused by free-fall installation using a laboratory-scale experiment, regression analysis, and numerical collision analysis

Several studies have identified stability issues related to artificial reefs (ARs) installed on the seabed. However, initial AR settlement during free-fall installation has not been well examined. We performed a laboratory-scale experiment, regression analysis, and numerical simulation to evaluate the initial settlements of two cube-type AR models during free-fall installation into soft soil. Settlement tended to increase by impact velocity and...
