...-cohesive layered soils, and the bearing capacity evaluation recommendations suggested by SNAME are not conservative for small size barge footings. Furthermore, improper simplification of shallow thin hard soil strata or poor interpreted soil strength parameters can lead to misjudge the possibility of punch...

... ABSTRACT Safe installation of mobile jack-up platforms requires accurate prediction of the vertical load-penetration curves of their large ∼20 m diameter spudcan footings. Difficulties can arise due to a change of soil strength from a soft to a stiff layer. A substantial increase...

Soil Rupture under a Strip Footing Subjected to Combined Loading Michael Cocjin, Osamu Kusakabe, Masaki Kitazume Department of Civil Engineering, Tokyo Institute of Technology Tokyo, Japan ABSTRACT Recent studies on combined loading of shallow foundations employ a force-resultant model as a means...

... ABSTRACT Estimating bearing capacity of foundations is one of the key issues in geotechnical practices. Footings have to be built on slopes or near the crest of slopes in some civil engineering practices. This study investigated the combined bearing capacity behavior of strip footings near...

... ABSTRACT: Foundation-soil interaction is an important aspect of site-specific assessment of jack-up drilling rigs. For jack-up operations in soft clays, deep penetration of the spudcan footings and soil backflow are common. This is generally expected to increase capacity, though to date...
