Evaluation of Stability of the Rock Slopes in Taiz City and Surrounding Areas of Yemen Using Slope Mass Rating (SMR) System and Kinematic Analysis Technique
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 9
Abstract
Assessment of stability of rock slopes is important to thwart the occurrence of landslides and consequent socioeconomic evils. The present maiden study is carried out in and around Taiz city known for geotechnical hazards by isolating 14 of 110 field stations located along road cuts, quarries and natural exposures representing varying lithological and geotechnical conditions. The stability of rock slopes was evaluated by applying the original Slope Mass Rating (SMR) system. The parameters of SMR system were measured based on field and laboratory investigations. The failure mode at each site and its potential failure directions were determined kinematically using the stereographical projection method employing Stereonet software. The obtained results from applying SMR system at 14 rock slope stations demonstrated that there are various modes of failure and a single slope may have been affected by more than one type of failure depending on the relationship between the discontinuities and slope face, discontinuity characteristics and lithological conditions. The calculated values of SMR show variations from 1.4 to 70.4 indicating that these values plot from "Very Bad" (Vb) class to "Good" class (IIb). The results also indicate the more scope for planner, toppling and/or big wedge failures and warrants suitable corrective measures, especially in the areas where the SMR values fall in IV and V classes. Further, slope Nos. 5 (zone-I) and 40 (zone-I) are "Stable" against wedge and toppling failures respectively and five slope locations (22, 36, 68, 76 and 86) are "Partially Stable" against toppling failures, while two rock slope locations (Nos. 77, 92 and 96) are "Unstable" against the various failures. The unstable slope locations vulnerable for planar/falling failure are 5, 30, 57, 76 and 86. The remedial measures to control slope failures in 14 slope locations are suggested based on SMR values.
