Effects of Soil Crust on Seismic Failure Behavior of Pile Group–Bridge System during Liquefaction-Induced Lateral Spreading: Large-Scale Shake Table Experiments
(ASCE, 7/21/2023 )Two large-scale shake table experiments were conducted to study the seismic pile group–bridge soil system failure mechanisms and examine the role of soil crust in lateral spreading caused by liquefaction. Pile group–bridge ... -
Large-Strain Consolidation Analysis for Clayey Sludge Improved by Horizontal Drains
(ASCE, 5/25/2023 )The use of prefabricated horizontal drains (PHDs) with combined surcharge and vacuum preloading is an effective improvement approach for dredged clayey slurries. However, there is no large-strain analysis method for ... -
A Bioinspired Self-Burrowing Probe in Shallow Granular Materials
(ASCE, 6/26/2023 )Bioinspired strategies have been used in recent years to solve engineering problems in geotechnics. Inspired by the dual-anchor locomotion mechanism of razor clams, researchers are developing a new generation of self-burrowing ... -
The Liquefaction and Cyclic Mobility Performance of Embankment Systems Constructed with Different Sand Gradations
(ASCE, 7/27/2023 )A broad range of coarse-grained soils that vary in gradation uniformities, maximum particle sizes, and absolute densities are prone to liquefaction during earthquake shaking. However, clean, poorly graded sands form much ... -
Behavior of Full-Scale U-Shaped Walls Constructed by Deep Cement Mixing in Consolidating Ground
(ASCE, 6/27/2023 )Deep excavations in soft clays often demand heavy shoring supports. Closely spaced struts are known to impede construction within an excavation, resulting in longer construction time. This paper presents a novel strut-free ... -
Calibration of Pore Pressure Model for the Liquefaction Prediction of Soils Based on Behavior of Clean Sand, Magnitude Scaling Factor, and Initial Stress Level
(ASCE, 5/27/2023 )The pore pressure model was developed in the past to predict liquefaction induced by an earthquake. Its main advantage is that its parameters can be obtained from experiments based on direct measurement of pore pressure ... -
Laboratory Testing of Construction-Induced Ground Displacements for Open Caisson Shafts in Sand
(ASCE, 8/4/2023 1)The development of underground spaces inevitably poses significant risks to nearby infrastructure due to construction-induced ground displacements. While our understanding of tunnel-induced ground movements is now relatively ... -
A CPT-Based Design Framework for Uplifted Open-Ended Piles Installed in Spatially Variable Sandy Soils. II: Implications to Site Investigation and Pile Design for Offshore Wind Farms
(ASCE, 8/29/2023 )Interpreting seabed properties for future offshore wind farm development appears challenging given the requirement to investigate very large areas. Current approaches, where significant numbers of geotechnical boreholes ... -
A Soil Hydraulic Conductivity Equation Incorporating Adsorption and Capillarity
(ASCE, 5/25/2023 )A soil’s hydraulic conductivity is a highly nonlinear function of water content, decreasing many orders of magnitude from its saturated state to dry state. This nonlinearity is a macroscopic manifestation of microscopic ... -
A CPT-Based Design Framework for Uplifted Open-Ended Piles Installed in Spatially Variable Sandy Soils. I: Soil Resistance Design Line Optimization
(ASCE, 8/29/2023 )Due to the mechanical properties of the seabed exhibiting horizontal and vertical spatial variability, an important challenge in offshore geotechnical design lies in the selection of the relevant soil strength profile for ... -
Bayesian Optimization for CPT-Based Prediction of Impact Pile Drivability
(ASCE, 8/31/2023 )Pile drivability predictions require information on the pile geometry, impact hammer, and the soil resistance to driving (SRD). Current SRD prediction methods are based on databases of long slender piles from the oil and ... -
A Framework for Assessing the Bearing Capacity of Sandy Coastal Soils from Remotely Sensed Moisture Contents
(ASCE, 7/27/2023 )The strength of partially saturated sand is critical for addressing engineering challenges such as beach trafficability or coastal erosion. Mapping strength remotely would allow for surficial geotechnical characterization ... -
