Assessing the Performance of Liquefaction Settlement Models Following Blast Testing in Silty Sands Open
Soil liquefaction can significantly impact the settlement and load-bearing capacity of soil, which in turn affects structural stability and safety. The increase in pore pressure from seismic events and its subsequent dissipation can lead t…

Developing Liquefaction Prediction Equations for Gravels Based on DPT Blow Count and Shear Wave Velocity at Field Case History Sites Open
Gravelly soils have liquefied at multiple sites in at least 20 earthquakes over the past 130 years. These gravels typically contain more than 25% sand which lowers the permeability and makes them susceptible to liquefaction. In other cases…

The first Italian blast-induced liquefaction test (Mirabello, Emilia-Romagna, Italy): description of the experiment and preliminary results Open
Soil liquefaction can result in significant settlement and reduction of load-bearing capacity. Moreover, the increase and the accumulation of pore pressure during an earthquake and its post-seismic dissipation can generate permanent deform…
