It is imperative to undertake a thorough investigation into the bearing capacity and comprehensive behaviors of GIAs in sand, given the marked disparity between the properties of sand and clay. Three parts of study are reported in this paper. First, a theoretical model is developed to analyze the comprehensive behaviors, including diving, keying and pulling out, and the whole trajectory of GIAs in sand. Second, a large deformation finite element model with the coupled Eulerian–Lagrangian (CEL) technique, embedded in a bounding-surface plasticity model that has the ability to reflect the strain hardening of loose sand and strain softening of dense sand, is established to analyze anchor behaviors in sand. Third, by combining theoretical and numerical models, two topics of GIAs in sand are investigated in detail, including the bearing capacities and the comprehensive behaviors. Being an important output, an explicit expression of the end-bearing capacity factor for both diving and pulling out is derived, in terms of the embedment depth, the soil property, the anchor orientation, the loading angle and the bearing area. Effects of various factors on the behavior of GIAs in sand are explored by parametric analyses. The results demonstrate that the anchor is susceptible to being pulled out rather than embedded in sandy seabed. The closer the shackle is to the anchor tip, the lower the soil strength is, and the closer the loading angle is to the horizontal, the easier the anchor is to be embedded in sand. The embedment depth has little effect on the anchor trajectory if the anchor reaches at least the embedment depth of 1.4 times of the fluke length. These findings are helpful to understand further the comprehensive anchor behaviors and to promote the application of GIAs in offshore engineering.</div></div>","PeriodicalId":19403,"journal":{"name":"Ocean Engineering","volume":"329 ","pages":"Article 121129"},"PeriodicalIF":4.6,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the penetration of tetrapod bucket foundations, soil flows both into and out of the foundation, leading to observable soil heave. Although soil heave within each individual bucket is similar to that of a single bucket foundation, the heave occurring between the four buckets is influenced by their separation distance. The penetration resistance of the tetrapod bucket foundation is composed of inner side wall resistance, outer side wall resistance and end bearing capacity. The inner side wall resistance and end bearing capacity are relatively unaffected by the separation distance, whereas the outer side wall resistance exhibits a certain degree of sensitivity to this parameter.

Then, a series of FE analysis is conducted to consider the effects of plate anchor aspect ratio, initial embedment depth, sand relative density and inclined loading angle on the pullout capacities. Results show that shallow anchors develop failure zones reaching the soil surface, and vertical pullout capacity exceeds that under pure vertical loading when the load is slightly inclined. For deep anchors, failure zones are confined below the surface, and horizontal pullout capacity exceeds that under pure horizontal loading when the load is slightly inclined.

The soil strength can be reduced by cyclic loads, potentially leading to failure of cage foundation. This paper proposes an integrated model to simulate the spatiotemporal interaction between the cage and the clayey seabed under wave action, obtaining the time-dependent response of the cage structure. The fluid-structure interaction is governed by the Morison equation and an advanced constitutive model, capturing the cyclic behavior of soil, is adopted for the foundation-seabed interaction.

To enhance training efficiency and introduce additional dependencies, we integrate an auto-regressive model into the residual block of TCN. Furthermore, TCN is embedded within a hybrid data-physics loss function, and a mini-batch learning strategy is implemented to optimize the performance of PITCN-AR. Finally, the efficacy and practicality of PITCN-AR are rigorously validated using both synthetic and real-world data.
