Energy-Based Evaluation and Remediation of Liquefiable Soils
Remedial ground densification is commonly used to reduce the liquefaction susceptibility of loose, saturated sand deposits, wherein controlled liquefaction is typically induced as the first step in the densification process. Assuming that the extent of induced liquefaction is approximately equal to …

Seismic behaviour of shallow foundations on layered liquefiable soils
… foundations resting on saturated sandy/silty<br/>soils has been repeatedly observed throughout the world as a consequence of<br/>liquefaction or softening of the foundation soil. Such settlements and tilts can<br/>render structures unusable, and homes uninhabitable, causing significant economic …

1-g Shake Table Experimental Evaluation of Building Settlements Founded on Liquefiable Soils
… density, ground motion duration and thickness of liquefiable layer. Experiments included use of accelerometers, pore water pressure sensors and linear variable differential transformers (LVDT) to monitor behavior in both free-field and model building footprints during induction of liquefaction. A …

The Seismic Response of Offshore Wind Turbines Supported by Monopiles and Alternative Foundations in Liquefiable Soils
… study of the seismic response of monopiles in liquefiable soils using both, centrifuge, and numerical modelling. The experimental setup designed for centrifuge testing aimed to reproduce a monopile supported OWT subjected to the combined action of earthquake induced liquefaction, dynamic …

Shear Modulus Degradation of Liquefying Sand: Quantification and Modeling
… earthquakes. Of all the different types of soil, liquefiable soils present some of the greatest challenges. The ability to quantify the degradation of a soil's shear modulus as it undergoes liquefaction would help engineers design more reliably and economically. This thesis uses ground motions …

Ground Improvement for Liquefaction Mitigation at Existing Highway Bridges
… on shallow foundations and underlain by thick, liquefiable soils with and without improved ground zones. Ground improvement that restricted movements of the pier and stub abutment to tolerable levels included improved zones of limited size extending completely through the underlying liquefiable …

Seismic Behaviour of Retaining Walls with Adjacent Structures
… by the failure of their foundations embedded in liquefiable soils. Additionally, despite the importance and seismic vulnerability of container cranes, a comprehensive understanding of their failure mechanisms has not been developed to produce reliable seismic designs of such structures. …

Numerical modeling of a bridge system & its application for performance-based earthquake engineering
… by soil conditions (e.g., competent soil or liquefiable soil) and loading conditions (e.g., earthquake intensity, motion characteristics, and shaking orientation). In this context, two bridges with different soil and loading conditions were considered focusing on different aspects of their …

Probabilistic Post-Liquefaction Residual Shear Strength Analyses of Cohesionless Soil Deposits: Application to the Kocaeli (1999) and Duzce (1999) Earthquakes
… The residual or liquefied shear strength of the liquefiable soils is a very important parameter when evaluating stability and deformation of level and sloping ground. Current procedures for estimating the liquefied shear strength are based on extensive laboratory testing programs or from the …

An Investigation into the Seismic Resilience of Shallow Cut-and-Cover Tunnel in Urban Environments
… dynamic behaviour of shallow-buried tunnels in liquefiable soils is critical for the seismic design of underground infrastructure, particularly in congested urban areas, where interactions with adjacent surface structures further complicate this dynamic soil-structure interaction (SSI). This …

The axial behaviour of piled foundations in liquefiable soil
… which can be mobilised by piled foundations in liquefiable soils when subjected to strong shaking remains highly uncertain, and a number of piled foundations have failed in strong earthquakes as recently as 2011 . The lack of visible foundation distress in many such cases indicates that failure …
