Caracterización geotécnica de suelos volcánicos relacionados con inestabilidades de ladera en Gran Canaria

Abstract

Geotechnical properties of volcanic soils in Gran Canaria (Spain) are be unstudied. We essay six samples, located in different part of the island principal road, to obtain geotechnical parameters to design slope stability models. Our results shows a great plasticity at the samples, with very various properties of cohesion, specific weight, composition, etc. All models we make reveals an important reduction in safety factor when increased the water level and use residual parameters. All models are made assuming a homogeneous a unique composition, one sample at each slope. All of them have a great safety factor, because that it can said that Gran Canaria haven’t stability problem near the principal road.
