Abstract: The hemiball penetrometer is a geotechnical device developed to measure the property of surficial seabed sediments (<0.5  m), which is of most significance for pipeline design and for situations in which traditional ...

Abstract: This paper proposes a new arrangement of geotextile reinforcement stiffness for large geotextile mat cofferdams that often suffer from the failure of the bottom layer mat. Cofferdams using this new reinforcement method are ...

Abstract: The use of the plasticity theory offers an attractive framework to encapsulate the behavior of a pipe and the underlying soil in terminology consistent with pipeline structural analysis. Models that express the pipe-soil ...

Abstract: This paper presents three plasticity models that can be applied to numerically simulate pipe–soil interaction. They can be applied individually to evaluate the force–displacement response of a small plane-strain pipe section ...

Abstract: The remeshing and interpolation technique with small-strain (RITSS) finite-element method has been widely adopted to address a broad range of two-dimensional (2D) large deformation geotechnical problems. However, its ...

Abstract: Suction caissons, widely applied in offshore engineering, suffer from significant uncertainties about the flow mechanism of the surrounding soil during installation, especially for caissons with ring stiffeners. Large ...

Abstract: The effect of soil spatial variability on the undrained vertical uplift capacity of plate anchors has been examined using the three-dimensional random finite-element approach. Multiple direct Monte Carlo simulations (MCS) ...

Abstract: This study presents a range of numerical modeling to evaluate the pullout capability of suction anchors subjected to inclined mooring loading in a clay-over-silty-sand deposit. Comprehensive numerical models were generated, ...

Abstract: A buried bucket foundation combined with a vertical truss is a new foundation system for photovoltaic farms in marine tidal flat (MTF) areas with deep soft soil. This paper employs numerical methods to study the response ...

Abstract: Spudcans are commonly installed to support jack-up vessels in construction process of offshore wind turbines (OWTs), which may induce significant soil deformation that may impact existing foundations of established OWTs. ...
