The sites were chosen by sediment type and propensity to liquefaction. Five tests were conducted at each location, establishing the drainage characteristics and strength of soil. Additionally, the study constructed a shake-box equipped with monitoring sensors, then filled the box with various kinds of soil that were experimentally shaken.
Comparison of sand behavior under repeated liquefaction in ...
The results showed that liquefaction resistance in the first shake event was always larger than the following event in every repeated liquefaction series. In addition, under the same input acceleration, the results revealed that future liquefaction resistance can be briefly predicted using current and previous maximum strain amplitude .

Potential Earthquake Hazards in Salt Lake County | Steven ...
Earthquake Hazard Along the Wasatch Front Salt Lake County faces many hazards from our impending earthquake. The estimated quake magnitude of 6.8 to 7.0 would cause severe shaking and soil liquefaction affecting every area in the county. Along the faults themselves the danger is from shake and landslide. In the center of the valley the dangers…

Earthquake Induced Liquefaction Using Shake Table Test
Prasad et al (2004) have developed a manual shake table using laminar box. However, it does not take into account pay load and the criterion for initiation of liquefaction in terms of CSR Behra K. C. et al ( 2005) studied liquefaction behavior of silty sand by conducting shake table tests on samples with different silt contents.
Study of Pre-Shake Effects on Liquefaction in Shake Table ...
The shear strain development in pre-shaking is peculiar and inferred as another governing factor in controlling the liquefaction and reliquefaction resistance of sandy soils (See figure 2, number of cycles means the liquefaction and reliquefaction resistance and figure 3 represents the formation of model in soil box on the shake table).

Predicting Liquefaction Displacements with Application to Field Experience Beaty, Michael H.', Byrne, Peter M.2 ABSTRACT Liquefaction has caused severe distress or failure to buildings, bridges and dams during seismic events. Such damage arises from the soil displacements occurring upon liquefaction.
