Earthquake Shaking in Alpine Valleys - Part 2 (SHAKE-VAL 2) - geotechnical laboratory tests for identification of cyclic soil parameters

Abstract:

IGT’s contribution in the framework of the project SHAKEVAL 2 is related to the parameter identification and determination for liquefaction prone soils. The parameters are needed as input parameters for different soil models for the modelling of wave propagation in the target areas of the SHAKE-VAL project in Wallis. In particular, the layers of soil prone to liquefaction will be modelled in the classical way using a linear equivalent elastic model as well as using a non linear model based on cyclic mobility.
Soil samples were take from the test site in Visp (VS) and were tested in the triaxial apparatus. In order to obtain the reqired soil parameters, test series of standard and cyclic shear tests as well as bender element tests were performed.
