Correlation of joint roughness coefficient (JRC) and peak friction angles of discontinuities of Malaysian Schists
The surface roughness of geological discontinuities plays an important role in influencing the stability of rock masses. Several approaches can be adopted for its determination.

| Summary: |
The surface roughness of geological discontinuities plays an important role in
influencing the stability of rock masses. Several approaches can be adopted for its
determination. This paper presents a simple approach whereby two polynomial
approximations have been derived to correlate the peak friction angle, f peak of discontinuity
planes of fresh as well as slightly weathered schist bedrock with the Joint Roughness
Coefficient, JRC |
