Slope failure occurs is when abrupt movement of slope material due to loss of shear strength where pore pressure and shear stresses increase. There are many factors that cause shear stress increase while chances of slope failure also increase. Different factors have respective processes lead to decrease shear strength of rock mass such as increase pore pressure, weathering, increase friction angle, cracking and above that. Shear stresses increase in rock mass due to surcharge of force from top of the slope, soil weight increase due to higher groundwater content at the top of the slope, undercutting and excavation at bottom of
