Research on the Uplift Bearing Capacity of Suction Caisson Foundation under Local Tensile Failure

The research on the uplift bearing capacity is one of the important issues worth concerning and solving. For this reason a lot of studies about this aspect have been done by many scholars, but there are still no wide spread engineering specifications on design and calculation of uplift bearing capacity for suction caisson foundation. The quantitative calculation method on the uplift bearing capacity of suction caisson foundation under local tensile failure is proposed by the author. And the indoor uplift tests are carried out on the single-bucket suction caisson foundation models with different diameters and length-diameter ratios in the wet sand, by which the feasibility of this method is initially proved.
