Abstract：The characteristics and failure mechanism of the Shilaoren Scenery Garden rock landslide along highway S212 in Qingdao city are investigated. On the basis of the rock landslide properties and the control requirement，a new kind of composite anti-sliding pile is used in the reinforcement engineering. The composite anti-sliding pile is composed of the general anti-sliding pile and the assembled drilled micro-steel tube piles，that is，the general anti-sliding pile is adopted in the seriously weathered rock layer of the sliding mass in view of the easy excavation，while the assembled drilled micro-steel tube piles are adopted in the moderate or slightly weathered rock layers in view of the hard excavation. The composite anti-sliding structure combines the general anti-sliding pile and the drilled mirco-steel tube piles to form an integrated structure，which is applicable to reinforcement of such similar rock landslide for the convenient construction and the large stiffness. The rock landslide reinforcement engineering has been proved successful in practice，and the application of the new kind of composite anti-sliding pile to the engineering has built up a successful example for control of the similar rock landslide.
