Proceedings Papers
Rapid evaluation of leaching potential of heavy metal elements from tunnel excavated rocks using handheld X-ray fluorescence spectrometer
Available to Purchase
Paper presented at the ISRM International Workshop on Rock Mechanics and Engineering Geology in Volcanic Fields, September 9–11, 2021
Paper Number: ISRM-IWRMEGV-2021-61
.... The result shows that changes in lithological description about color, weathering and hydrothermal alteration are represented by changes in covariation of heavy metal elements with other elements, such as between As and S, Fe and Mn. The horizontal variation of As composition by handheld-XRF of the core...

Geotechnical Description of Halloysite Clays From La Palma Island (Spain)
Available to Purchase
Paper presented at the ISRM International Workshop on Rock Mechanics and Geoengineering in Volcanic Environments, May 31–June 1, 2010
Paper Number: ISRM-IWVE-2010-003
... Ba4w1. S-0 I I BQtaMle SO Figure 9. Clay content variation in the different boreholes. This abnormality in the results was caused by the physic-chemist characteristics of halloysite. The cylindrical shape of halloysite particles makes water inflow in the structure to be quite complex and slow, so...

A Sensitive Analysis on Mohr-Coulomb and Hoek-Brown Parameters Effective in Ground Response Curve
Available to Purchase
Paper presented at the ISRM International Workshop on Rock Mechanics and Geoengineering in Volcanic Environments, May 31–June 1, 2010
Paper Number: ISRM-IWVE-2010-015
..., it can be concluded that Mohr-Coulomb criterion is more sensitive in respect O f variation of strength parameters of rock mass than Hoek-Brown. 1 INTRODUCTION Analysis of stresses and displacements around circular opening that excavated in isotropic rock masses has been one of the fundamental problems...
