    Abstract

    Submarine slope instability is one of the most concerned geohazards in offshore engineering due to its serious threat to offshore infrastructure. In shallow waters the submarine slope subjected to wave-induced pressure may undergo significant movements, which needs to be considered in the routine design of pipelines or spudcan footing to support jack-up rigs. To evaluate the stability of seafloor slopes, in this paper, the limit state equation based on the upper bound approach of limit analysis incorporating strength reduction technique is established. The wave-induced pressure on the slope is applied as external loading. The minimum safety factor is obtained by searching the critical sliding surface. The effect of wave loading on the stability of seafloor slopes is quantified. © 2015 Taylor & Francis Group, London.
