Electrical resistance tomography of the large block test near yucca mountain

摘要

The Large Block Test (LBT) is being conducted near Yucca Mountain to study the hydrothermal,thermomechanical,and thermochemical responses of the Topopah Spring tuff.This paper describes electrical resistance tomography (ERT) surveys made during the LBT to map the changes in electrical resistivity caused by temperature and moisture changes in the rock.The electrical resistivity data will be used together with the temperature field to ma the movement of condensate within the block during heating and cooling.
