Mechanical behavior of volcanic rocks

摘要

Some relevant aspects related to the mechanical behavior of volcanic rocks are considered, mainlyrnbased on laboratory tests performed on rocks from the Canary Islands. Ranges of variation of the most relevantrngeotechnical parameters from the point of view of mechanical behavior and some correlations are given forrndifferent types of rocks. More attention is paid to the analysis of pyroclastic rocks, as their mechanical behaviorrnis more peculiar. An empirical yield criterion for low density pyroclasts is adjusted to test results.
