... ABSTRACT Physical modelling of trench infill, for trenches perpendicular to the flow direction, was undertaken in the Fast Flow Facility at HR Wallingford. Parameters including trench width, flow velocity (including reversing tidal flow), and the presence of berms along the sides of the trench...

.... In these applications, the diameter to wall thickness ratio (D/t) ranges between 60 and 140. The main loading is bending in combination with normal force, earth loads and tensile or compressive loads from the infill sheeting. The governing failure mode is local buckling in the inelastic range of the steel. The current...

... Abstract Thin metal or reinforced concrete shells with granular infill structures are considered in this article. These structures are massive and they are used as support for the construction of berthing quays, piers, artificial islands, shore protection, and other structures of coastal...

... Abstract A description of finite element model and analysis of a shell with an infill is performed. A large diameter thin cylindrical shell structure with the edge leaning against compressible foundation soil is analyzed. Different materials are considered individually for the models of each...

... combined with uneven seabed may lead to significant seabed intervention costs for many small diameter pipelines as it is required to keep the trawl loads and associated response within acceptable limits. Normally, seabed intervention is specified in terms of rock infill in free spans which will reduce...

..., and maintenance of the fragile environment in general, including cold water corals. Traditional design approach has called for infill of free spans and trenching of smaller diameter flowlines to eliminate damage risk from trawl gear interaction. On very irregular seabed this may lead to excessive intervention...
