CORRELATION OF MICROSTRUCTURE CHARACTERISTICS WITH THE SLOPE STABILITY AT TRUSMADI FORMATION, SABAH, MALAYSIA

This study focuses on the influence of weathered rock’s microstructure and its effect to the stability of slope at the Trusmadi Formation. Trusmadi Formation (Palaeocene to Eocene age) had experience a slightly metamorphism process and makes it highly susceptible to instability. Regional metamorphism that happened during tertiary has given rise to the formation of argillaceous rock. This rock then suffering a weathering process that change them to soil. Four samples were collected based on fail slope and stable slope. These samples were analysed using polarizing microscopic and scanning electr... Mehr ...
