ASEAN Journal on Science and Technology for Development, 2011 The basic friction angle, Φb for artificially sawn discontinuity planes for fresh granite, as determined by tilt testing, has an average value of 30º. For the natural rough discontinuity surfaces, a wide range of values have been determined for the peak ...

Correlation between joint roughness coefficient (JRC) and statistical roughness parameters [PDF]
peer reviewedRocks are heterogeneous anisotropic media containing discontinuities that influence their mechanical behavior through their surface morphology, aperture, and filling material. Surface morphology is generally characterized by roughness, which

The Influence of Different Shear Directions on the Shear Resistance Characteristics of Rock Joints
Buildings, 2023 The joint roughness coefficient JRC of rock joints is an important parameter for measuring the geometric morphology of rock joints. However, the parameter obtained from traditional calculation methods has certain limitations in reflecting the differences

American Journal of Agricultural Economics, EarlyView.Abstract Discrete choice experiments are increasingly being used to estimate land managers' willingness to accept participation in incentive‐based environmental programs. This is a specific application of discrete choice experiments: the estimation of willingness to accept for a private good (program participation) where respondents have to make trade ...
