Abstract
Primjena metode konačnih razlika u određivanju utjecaja statičkog posmičnog naprezanja na likvefakciju tla
Highlights
Soil liquefaction potential is mainly estimated by Seed and Idriss’s [1] “simplified procedure”; there are several other estimation methods that consider excess pore water pressure generation [2, 3]
The cyclic resistance ratio factor (CRR) values for the stress state appearing at the site and the reference CRR values are multiplied by the correction factor Kα
Gn is multiplied by the depth to find the mass of the soil column. This mass is multiplied by amax to find the maximum shear stress that occurs during the earthquake
Summary
Soil liquefaction potential is mainly estimated by Seed and Idriss’s [1] “simplified procedure”; there are several other estimation methods that consider excess pore water pressure generation [2, 3]. Structures on level sites create base shears, i.e., initial static shear stress The effects of this initial (static) shear stress on liquefaction potential of the underlying soil is discussed in [4,5,6,7,8,9,10]. Before these studies, a still-valid correction factor (Kα) was proposed in [11], to take the effects of these initial (static) shear stresses into account.
