Horizontal Bearing Capacity of A New Bucket Foundation with Partial Inclined Wall
The traditional bucket foundation use vertical wall, which like a cup is buried upside down in seabed. A new bucket foundation with partial inclined wall has been proposed in this article. Based on limit equilibrium analysis of threedimensional stress state of foundation, the calculation method of the horizontal bearing capacity of the new bucket foundation has been deduced, which has been veri...
متن کاملEffect of the Spudcan’s Footprints on Nearby Jacket’s Mudmat in Clayey Soil-Case Study
When a jack-up installed at a clay location and then leaves; it can create several meter deep footprints. In case of soft clay, the spudcan may have actually penetrated much deeper than the observed footprints. When the penetrated spudcan is pulled out, much of the soft remolded clay will flow around it and go back into the hole. This event, leaving a deep region of disturbed soil. The disturbe...
متن کاملReliability Analysis of Jack-up Platforms Based on Fatigue Degradation
Generally, jack-up structures are used for production drilling and exploration of hydrocarbons. The combination of mobility and the behavior as a fixed structure in operational conditions has made it an important structure in the offshore industry over the last 40 years. When a jack-up structure has been in operation for a great part of its original design-life and intention is there to extend ...
متن کاملA comparison of the combined load behaviour of spudcan and caisson foundations on soft normally consolidated clay
Experimental data from loading tests of model circular footings on soft normally consolidated clay are presented. The experiments were carried out on a drum centrifuge at a radial acceleration level equivalent to 100 times Earth’s gravity, ensuring conditions of stress similitude between the model and the prototype scale. The aim of the experiments was to compare the undrained response of diffe...
متن کاملStudy on Load-Bearing Characteristics of a New Pile Group Foundation for an Offshore Wind Turbine
Because offshore wind turbines are high-rise structures, they transfer large horizontal loads and moments to their foundations. One of the keys to designing a foundation is determining the sensitivities and laws affecting its load-bearing capacity. In this study, this procedure was carried out for a new high-rise cap pile group foundation adapted to the loading characteristics of offshore wind ...
