An experimental study of salt/heat transport in a fracture-matrix system based on the resistivity method

open access: yesShuiwen dizhi gongcheng dizhi, 2023
In order to explore the effectiveness of salt and heat tracers in a fracture-matrix system, a fracture-matrix test model is designed. The tracer tests with different tracers are carried out.

3D Discrete Fracture Network Modelling from UAV Imagery Coupled with Tracer Tests to Assess Fracture Conductivity in an Unstable Rock Slope: Implications for Rockfall Phenomena

open access: yesRemote Sensing, 2023
The stability of a rock slope is strongly influenced by the pattern of groundwater flow through the fracture system, which may lead to an increase in the water pressure in partly open joints and the consequent decrease in the rock wall strength.
