... ABSTRACT Torpedo anchor is a promising novel offshore anchor foundation for deep-water floating facilities due to its efficient and economical installation. The pullout resistance of torpedo anchor is thus key for the stability of mooring system. The pullout performance of torpedo anchor...

... structures. Previous researchers were studied about the pullout resistance characteristics of piles using experimental model tests, field tests and numerical analysis. Meyerhof (1959, 1968, 1973, 1976) suggested that the pullout resistance of the pile is occurred due to the frictional force between the pile...

... ABSTRACT This study demonstrates the effect of the rate of applied loads on the pullout resistance and the generated suction pressure of anchor in terms of a laboratory model and field tests in sandy soils. Both tests clearly showed the pullout resistance tends to increase with increasing...

To achieve this purpose, the hull of the platform needs to be lowered...

... to about 60% and were horizontally pulled out to 70 mm displacement. In order to analyze the length effect of chain links, the number of anchor chain links was varied from 1 to 18. The cyclic pullout resistance converged to a certain value after sufficient number of pullout cycles and it was smaller than...

... diameter. From this observation it might be concluded that it is more efficient to increase the length of a suction pile rather than diameter to improve the capacity. model suction pile experiment centrifugal model behavior petrasovit diameter cohesionless soil pullout resistance prasad...

... resistance compared to other reinforcements. A series of cyclic pullout tests was performed in this study to investigate pullout resistance of reinforcements with expanded ends under cyclic pullout conditions. Pullout resistance and behaviors of reinforcements with/without expanded ends were compared...

... to provide baseline data. The results showed that the pullout resistance of the foundation model increased by 119% in phase "A" and by 214% in phase "B" of the treatment as compared with the control.

... ABSTRACT This paper presents a comparative study among the pullout resistances of different reinforcements for effective design of reinforced soil structures. Pullout tests on various reinforcing materials revealed that the pullout stress of the geogrid is larger than that of the geosynthetic...

... of the treatment were assessed by a pullout resistance test. After the pullout test, the caisson was pushed back into the soil sample and the treatment was repeated to simulate post-failure recovery.

In this paper, the authors present a basic design concept for steel grid reinforced earth walls, in which the bearing capacity type equation is used to estimate the pullout resistance...

... (Bergado et al. 1996). Such a limitation in backfill materials sometimes prevents to apply them, because of lack of ideal backfill materials. In contrast, the grid-type reinforcements have not such a severe limitation in back fill materials, because they have more pullout resistance than strip-type...
