Geotechnical characterization of rocky materials from Arteara rock avalanche (Gran Canaria)

Abstract

This work discusses the laboratory geotechnical characterization made with rocky materials coming from the Arteara rock avalanche, situated in Gran Canaria island. The study is based on laboratory test obtained for seven different lithotypes. The aim of them is to define strength and deformational parameters enabling subsequent modelling of the avalanche. The laboratory tests carried out included: the determination of porosity and absorption of the rock, the measurement of wave propagation speed, the evaluation of the strength in triaxial compression tests made in a Hoek cell and the shear strength in direct shear tests.
