Quantifying Residual Resistance of Light Pipelines during Large-Amplitude Lateral Displacement Using Sequential Limit Analysis
Publisher: ASCE
Abstract: The design of on-bottom pipelines regarding thermally induced lateral buckling requires a comprehensive understanding of large deformation lateral pipe–soil interactions to ensure that lateral buckles form as planned. This ...
Modeling Cyclic Embedment of Deep-Water Pipelines Using Large Displacement Limit Analysis
Publisher: American Society of Civil Engineers
Abstract: The as-laid embedment is a key design element of deep-water pipelines, as it significantly affects the longitudinal and transverse pipe–soil interaction and thermal insulation. Due to the small-amplitude oscillations driven ...
Modeling Cyclic Embedment of Deep-Water Pipelines Using Large Displacement Limit Analysis
Publisher: American Society of Civil Engineers
Abstract: The as-laid embedment is a key design element of deep-water pipelines, as it significantly affects the longitudinal and transverse pipe–soil interaction and thermal insulation. Due to the small-amplitude oscillations driven ...
Physical Modeling of Hydrate Dissociation in Sandy Sediment by Depressurization under Hypergravity and Normal Gravity Conditions
Publisher: American Society of Civil Engineers
Abstract: Geomechanical and heat transfer characteristics of gas hydrate-bearing sediment (GHBS) are significantly affected by hydrate dissociation during gas production from reservoirs, which is typically tens of meters in thickness. ...
Centrifuge Modeling of Monotonic and Cyclic Lateral Behavior of Monopiles in Sand
Publisher: ASCE
Abstract: This paper presents a program of centrifuge model tests (100g) on the monotonic and cyclic lateral loading behavior of monopiles. The diameter and burial depth of the model pile were 59 and 550 mm, respectively, and ...
Theoretical Investigation into Thermo-Osmosis and Thermofiltration Effects on Hydromechanical Behavior of Saturated Soils
Publisher: ASCE
Abstract: A change in temperature induces thermo-osmosis (T-O) and thermofiltration (T-F) effects in soils, which can influence consolidation under certain conditions. Whether such conditions are met is not always known a priori. ...
