ABSTRACT. This paper discusses the stability and to propose preliminary rock cut slope protection and stabilization measures for the Oligocene to Late Miocene Temburung Formation along the Beaufort-Tenom railway, Sabah. Nine (9) slopes were selected for this study. Geological mapping, discontinuity survey, kinematic analysis and prescriptive measures were used in this study. Result of this study conclude that the mode of failures are wedge, planar, circular and complex types. Gunite, soil nails, wire mesh, weep holes, subsurface drainage, slope reprofiling, terracing and surface drainage are proposed stabilization and protection measures for the slope in study area.
KEYWORDS. Temburung Formation, Beaufort-Tenom, Railway, slope stability, mode of failure.
