Kinematic And Block Theory Applications To Rock Slope Stability Analysis At Fraser's Hill Pahang Malaysia

摘要

The granite rock mass at cut slope located at the start of the entry road to Fraser's Hill in Pahang, Malaysia is characterized by a number of major and minor discontinuities. The persistence of most of these major discontinuities is expected to be between 15 m and 50 m. These discontinuities have been mapped at the mentioned site within and area covering 50 m × 400 m. The major discontinuities were used to perform a kinematic and block theory analysis of the rock slope stability. The kinematic analysis has been used in order to find the stability of the granite rock for cutting the rock slope at Fraser's Hill. The block theory has been applied to identify the different block types found at the surface of researched area and to estimate the maximum safety angle of the rock slope at the researched area. The orientations of the major discontinuities that occur in the researched area have been considered in this analysis. Which the data have been taken. The data was analyzed by stereo-plot and then analyzed using kinematic to determine the maximum safe slope angle (MSSA) for the rock slope and block theory to determine the key blocks types (Type Ⅰ) and potential key blocks types (Type Ⅱ) of the rock slope. The main purpose of this study is to determine a safe angle for the rock slope at entry road cut slope Fraser's Hill.
