Numerical Modeling of Liquefaction-Induced Downdrag: Validation against Centrifuge Model Tests
Publisher: ASCE
Abstract: Earthquake-induced soil liquefaction can cause soil settlement around piles, resulting in drag load and pile settlement after shaking stops. Estimating the axial load distribution and pile settlement is important for ...
Displacement-Based Design of Axially Loaded Piles for Seismic Loading and Liquefaction-Induced Downdrag
Publisher: ASCE
Abstract: Axially loaded piles in liquefiable soils can undergo severe settlements due to a shaking event. During shaking, the settlement is caused by the reduction of its shaft and tip capacity from the excess pore pressures generated ...
Centrifuge Model Tests of Liquefaction-Induced Downdrag on Piles in Uniform Liquefiable Deposits
Publisher: ASCE
Abstract: Earthquake-induced soil liquefaction can cause settlement around piles, which can translate to negative skin friction and the development of drag load and settlement of the piles. A series of centrifuge model tests were ...
Effects of Excess Pore Pressure Redistribution in Liquefiable Layers
Publisher: ASCE
Abstract: Existing simplified procedures for evaluating soil liquefaction potential or for estimating excess pore pressures during earthquakes are typically based on undrained cyclic tests performed on saturated soil samples under ...
Centrifuge Tests of Cone-Penetration Test of Layered Soil
Publisher: ASCE
Abstract: Two centrifuge model tests were used to examine the effect of soil interlayering on the measured cone-penetration resistance in a layered soil model. The first centrifuge model included four soil profiles: two uniform loose ...
