Investigation of scour effects on the vertical bearing capacity of suction caissons considering stress history
Suction caisson is one of the important forms of marine foundation. It is worthwhile to study scour effects on the vertical bearing capacity of suction caissons, which can provide a reference for the design of multi-caisson foundations. This paper investigated the influence of scour depth, stress history, and aspect ratio on the vertical bearing capacity of suction caissons. The capacity decreases with increasing scour depth, and its scour sensitivity is lower compared with the pull-out response. The capacity after scour is larger when the stress history is considered, so ignoring the stress history leads to a conservative design. The greater the aspect ratio, the greater the scour effect on the capacity. Based on these, an empirical formula for evaluating the vertical bearing capacity of suction caissons after scour is established, which reveals the relationship between the capacity and the scour depth and aspect ratio.
