Soil liquefaction occurs when a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress such as shaking during an earthquake or other sudden change in stress condition, in which material that is ordinarily a solid behaves like a liquid.

Soil liquefaction

In this paper, the peak kinetic energy density KED of soil particles during earthquake excitation is used as an intensity measure for the evaluation of liquefaction potential under field conditions. The paper seeks to discuss this measure. Using centrifuge tests data, it is shown that seismic pore water pressure buildup is proportional to cumulative KED at a particular soil depth.

Linear relationships are found between cumulative kinetic energy and corresponding cumulative strain energy. To consider the effect of soil amplification, several equivalent linear ground response analyses are performed and the results are used to derive an equation for depth reduction factor of peak kinetic energy density. Two separate databases of liquefaction case histories are used in order to validate the proposed model. Finally, the logistic regression method is employed to obtain probabilistic boundary curves based on the present model.

Parametric study of the proposed probabilistic model is carried out to verify its agreement with the previous methods. The results of the probabilistic kinetic energy model are in good agreement with those of previous studies and show a reasonable trend with respect to the variations of fines content and effective overburden pressure.

The proposed model can be as used an alternative approach for assessment of liquefaction potential. Jafarian, Y. Emerald Group Publishing Limited. Report bugs here.

Ground Motions and Soil Liquefaction During Earthquakes

Bulletin of the Seismological Society of America ;; 96 1 : — The prefactor corresponds to a threshold energy for liquefaction ranging from 0. The value of the threshold energy suggests a preliquefaction degradation of the shear modulus of soils by more than 3 orders of magnitude. Liquefaction documented during underground explosions is characterized by a threshold energy several orders of magnitude greater than that for liquefaction during earthquakes but shows a similar functional relation between E and R max as that for liquefaction during earthquakes and implies a similar attenuation relation between ground-motion energy density and distance.

Contributions are not limited exclusively to Latin American issues. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two receding years. SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field.
