Abstract	Brom (1975) thought that there are four types of failure for natural slopes. This paper aims to summarize the engineering measures to protect the slope from collapsing in the four types. Then Bishop Method is compared with Fellenius Method with an example. Friction pile can prevent deep-seated sliding. Friction piles with anchoring and shotcreting can improve the working performance of single friction piles. Retaining wall can provide resisting force to prevent the sliding of slope. Geosynthetics reinforced soil shear strength increases and the slope safety factor increases. Loading berm and and slope cutting can decrease the slope ratio and increases the safety factor. Enrockment and rubble can be built on slope surface to protect the slope surface from corroding from water. Drainage facilities in slope can decrease the water pressure and enhance the safety factor. For large areas, zoology protective technology for soil slopes is economic and effective. Results indicate that the safety factor provide by A. N. Bishop method is bigger than the safety factor provide by W. Fellenius for the same possible rotational sliding surface.
