Liquefaction Susceptibility of Uncemented Calcareous Sands From Puerto Rico by Cyclic Triaxial Testing
… tests were performed to investigate the liquefaction susceptibility of uncemented calcareous sands. A series of isotropically consolidated undrained monotonic and cyclic triaxial tests were performed using the Playa Santa sand from Porto Rico. Playa Santa sand is a poorly graded …

Liquefaction Analysis of Level and Sloping Ground Using Field Case Histories and Penetration Resistance
Lastly, the author proposed a comprehensive liquefaction analysis procedure for sandy soils to evaluate liquefaction susceptibility, liquefaction triggering, and post-triggering stability. The procedure incorporates the proposed relationships to estimate yield and liquefied strength ratio, and does …

Case history-based analysis of liquefaction in sloping ground
Liquefaction is one of the most interesting and controversial phenomenon in geotechnical engineering. This phenomenon has caused numerous slope failures in saturated deposits of fine, loose sands and other cohesionless soils. Because of the catastrophic nature of the failures and their impact on …

Assessment of Seismic Hazards along the Northern Gulf of Aqaba
… of active faults and by mapping areas of high liquefaction susceptibility. Ground Penetrating Radar (GPR) as a high resolution shallow geophysical tool was used to map the shallow active faults in Aqaba, Taba Sabkha area, and Elat. The GPR data revealed the onshore continuation of the Evrona, …

Modeling Liquefaction-Induced Road Disruptions in Cascadia Megathrust Earthquakes: Implications for Emergency Response and Access in the U.S. Pacific Northwest
… (CSZ) are expected to trigger widespread soil liquefaction that could severely disrupt transportation systems across the U.S. Pacific Northwest. However, past regional assessments have relied on simple geologic screening methods and binomial shaking thresholds that are only loosely informed by …

Application of Fatigue Theories to Seismic Compression Estimation and the Evaluation of Liquefaction Potential
Earthquake-induced liquefaction of saturated soils and seismic compression of unsaturated soils are major sources of hazard to infrastructure, as attested by the wholesale condemnation of neighborhoods surrounding Christchurch, New Zealand. The hazard continues to grow as cities expand into …

Liquefaction behavior and dynamic properties of loessial (silty) soils
… investigation has been made to ascertain the liquefaction (cyclic strength) behavior of loessial (silty) soils. No information on the mechanism governing the behavior of these soils under cyclic loads was previously available. This study is important in view of the seismicity of the …

Seismic parameters for the central United States based on paleoliquefaction evidence in the Wabash Valley
… Madrid Seismic Zone. Recent discoveries of paleoliquefaction evidence outside that Zone suggest prehistoric earthquake magnitudes in the Wabash Valley far exceed historical events. This geotechnical engineering study of paleoliquefaction sites in southern Indiana and along the Wabash River in …

Seismic behaviours of adjacent building structures on liquefied soil
… shaking was observed at the ground surface when liquefaction occurs. The amount of reduction in soil amplification can be derived. The peak excess pore water pressure profile can be predicted by a modified simple liquefaction susceptibility analysis. The reduction in ground intensity can also be …

Energy-Based Evaluation and Remediation of Liquefiable Soils
… 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 the extent …
