El documento describe métodos propuestos por barton y choubey en 1977 para obtener el índice de rugosidad de una junta (jrc) mediante ensayos de inclinación de bloques de roca asociados a los … The parameters j r and j a, given in tables 8. 3 and 8. 4, respectively, represent roughness and degree of alteration of joint walls or filling materials. The parameters j r and j a should be obtained for the …
The ratings of the various input parameters to the q-value are given in table 1. The q-value is related to tunnel support requirement by defining the equivalent dimensions of the underground opening. Para las masas de roca competentes (categoría 2 de srf), las nuevas clasificaciones de srf se enumeran en la tabla 9 como lo propuso grimstad y barton (1993). El srf debe ser clasificado de … Suggest srf increase from 2. 5 to 5 for low stress cases. Joint roughness number and joint alteration number (j r and j a) the parameters j r and j a, given in tables 8. 3 and 8. 4, respectively, represent roughness and degree of alteration of joint walls or filling … Modulus of deformation of rock mass is dependent on many factors such as nature, extent of discontinuities, aperture of joints, joints infilling, grain size distribution and weathering etc
