CORRECTION OF ROCK SLOPE ANGLE USING SMR MODIFICATION
To determine the rock slope stability requires optimum value of slope angle obtained through Slope Mass Rating (SMR) value. A research on SMR has been done by previous researchers namely Laubscher (1975), Hall (1985), and Orr (1992). However, the angle values obtained from the three typically var...

| description | To determine the rock slope stability requires optimum value of slope angle obtained through Slope
Mass Rating (SMR) value. A research on SMR has been done by previous researchers namely
Laubscher (1975), Hall (1985), and Orr (1992). However, the angle values obtained from the three
typically vary and are not suitable for some locations. Therefore, correction of the variation across the
SMR value obtained is necessary. The study was conducted based on the RMR value obtained through
the field data in the andesite quarry site Jelekong, West Java or using secondary data from previous
researchers. Based on the correction of the data obtained SMR equation as follows: SMR = 6.9209
RMR0.5323; R² = 0.92. From the equation obtained the optimum value of angle recommended for the
slope design with the following criteria (1) Very Poor Rock Quality: the slope angle is stable at a slope
of <34.09°, (2) Poor Rock Quality: the slope angle is stable at a slope of 34.99° – 49.31°, (3) Medium
Rock Quality: the slope angle is stable at a slope of 49.96° – 61.19°, (4) Good Rock Quality: the slope
angle is stable at a slope of 61.72° – 71, 31°, (5) Very Good Rock Quality: the slope angle is stable at
a slope of 71.78 ° – 80.30 °.
