“…Compared with field tests, more and more centrifugal model tests have been applied recently in various engineering due to its virtue of quick construction and low engineering cost. Simultaneously, the results of centrifugal model tests are consistent with those of field tests, which had been confirmed by a large number of studies, suggesting that centrifugal model tests have a certain accuracy and reliability [27][28][29][30][31][32].…”

This study aims at investigating the effect of steel casing on vertical bearing characteristics of steel tube-reinforced concrete piles in loess area by centrifugal model test. Five piles were selected, one of them was a conventional reinforced concrete pile which was 35 cm in length and 2.5 cm in diameter as a contrast pile, and the length of steel casing for the remaining four steel tube-reinforced concrete piles was 8 cm, 12 cm, 16 cm, and 20 cm respectively. The results show that the axial force, unit skin friction, tip resistance, and shaft resistance of steel tube-reinforced concrete piles with different steel casing lengths were different from conventional reinforced concrete pile. Additionally, the ultimate bearing capacity of steel tube-reinforced concrete piles was compared with a conventional reinforced concrete pile. Moreover, advantages of steel casing in pile foundation engineering were summarized. The results of this study can provide reference for vertical bearing characteristics of steel tube-reinforced concrete piles in loess area.

“…Some studies about the suction anchor capacity were focused on sand (Bang et al, 2011;Deng & Carter, 2000;Gao et al, 2013;Jang & Kim, 2013;Liu et al, 2015;. Bang et al (2011) conducted centrifuge model tests to obtain the suction anchor capacity in sand, and proposed an analytical solution of anchor horizontal pull-out capacity.…”

The deep‐sea ground contains a huge amount of energy and mineral resources, for example, oil, gas, and minerals. Various infrastructures such as floating structures, seabed structures, and foundations have been developed to exploit these resources. The seabed structures and foundations can be mainly classified into three types: subsea production structures, offshore pipelines, and anchors. This study reviewed the development, installation, and operation of these infrastructures, including their structures, design, installation, marine environment loads, and applications. On this basis, the research gaps and further research directions were explored through this literature review. First, different floating structures were briefly analyzed and reviewed to introduce the design requirements of the seabed structures and foundations. Second, the subsea production structures, including subsea manifolds and their foundations, were reviewed and discussed. Third, the basic characteristics and design methods of deep‐sea pipelines, including subsea pipelines and risers, were analyzed and reviewed. Finally, the installation and bearing capacity of deep‐sea subsea anchors and seabed trench influence on the anchor were reviewed. Through the review, it was found that marine environment conditions are the key inputs for any offshore structure design. The fabrication, installation, and operation of infrastructures should carefully consider the marine loads and geological conditions. Different structures have their own mechanical problems. The fatigue and stability of pipelines mainly depend on the soil‐structure interaction. Anchor selection should consider soil types and possible trench formation. These focuses and research gaps can provide a helpful guide on further research, installation, and operation of deep‐sea structures and foundations.

“…All the analyses are conducted for 5%, 25%, 50%, 75% and 95% mooring positions. Only one value of  (=0) is used and the results are compared with the centrifuge tests results by Jang and Kim (2013) where the applied load was in the lateral direction. The soil parameters used in the analysis are listed in Table 1.…”

“…Some centrifuge tests have been conducted in the past to understand the pullout behavior of caisson in sand (e.g. Allersma et al, 2000;Lee et al, 2003;Kim et al, 2005;Jones et al 2007;Kim et al, 2009;Kim et al, 2010;Bang et al, 2011;Jang and Kim 2013). Bang et al (2011) reported a series of centrifuge tests at 100g on a model suction caisson in medium dense sand to evaluate the pullout capacities.…”

Three-dimensional finite element (FE) analyses are conducted to calculate the pullout capacity of suction caisson subjected to oblique loadings. Two sets of FE analyses are performed using Abaqus FE software. In the first set, the sand around the caisson is modeled using the built-in Mohr-Coulomb model (MC) available in Abaqus where constant values of angle of internal friction () and dilation () are defined. The effects of key variables, such as loading angle, mooring position and aspect ratio, on pullout capacity and rotation of the caisson are examined. A comparison between FE and centrifuge test results is also shown. The second set of analyses are performed using a modified Mohr-Coulomb model (MMC) where the pre-peak hardening, post-peak softening and effects of density and confining pressure on stress-strain behavior of dense sand are implemented using a user subroutine by varying  and  as a function of plastic shear strain and confining pressure. Comparing the failure surface development in the soil with increase in loading for two different models (MC and MMC) it is shown that the mobilized  and  varies along the failure planes if the MMC model is used, although the capacity of the caisson could be obtained even if appropriate values of constant  and  are used in the MC model.
