对青岛市S212公路上石老人观光园段岩石滑坡的基本特征及其成因进行分析,根据该岩石滑坡的特征及治理工程的要求,在治理工程中采用了一种新型复合抗滑桩结构.该复合抗滑结构由普通抗滑桩和微型钻孔钢管组合桩共同构成,即在滑体等易开挖的强风化岩层中采用普通抗滑桩,而在嵌固段等不易开挖的中～微风化岩层中采用微型钻孔钢管组合桩.该复合抗滑结构将普通抗滑桩和微型钻孔钢管组合桩结合为一个有机整体,施工安全方便,同时又具有较大的刚度,特别适合类似岩石滑坡的治理.实践证明该岩石滑坡的治理效果较好,这种新型复合抗滑桩结构的应用为今后类似岩石滑坡工程的治理提供了成功的范例.

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.
