Abstract

Aiming at improving the knowledge on the source areas of shallow landslides, this research deals with the geotechnical characterization of the debris slope cover of arenaceous formations, by means of low cost dynamic penetration tests (Dynamic Probing – DP).

The knowledge of strength parameters of this material is fundamental to understand the triggering mechanisms of the shallow landslides. Therefore, in order to determine the typical values of relative density (D_R) and internal friction angle (φ′), many tests were performed and the results of 132 Dynamic Probing tests, 74 Standard Penetration Tests (SPT) and 14 laboratory shear tests, were analysed. The comparison between the φ′ values obtained by DP tests with those resulting from direct shear tests evidenced a good linear correlation. This confirmed the satisfactory and repeatable results of DP tests. Therefore, Dynamic Probing can be an effective, simple, practical and inexpensive tool for the geotechnical characterization of hazardous slopes.
