抄録

A study has been carried out on estimation of flow in rock joint using depth-averaged flow model. Based on the results from an idealized sinusoidal rock joint roughness, it is found that the hydraulic conductivity of rock joints is strongly affected by both aperture and joint surface roughness. The model proposed herein has shown its ability in simulating the flows on rock joints especially for small shear displacement with comparison to experimental results. However, it is recommended that more research has to be carried to investigate on how the effect of wall roughness deformation due to shear displacement can be accommodated in the model.
