Stabilisation of a legendary hanging cliff

Pyramid hill in southern taiwan has two monkey face like rocks on its western slope. Local folks consider the rocks as a scenic landmark. There are also legends about these rocks. During the construction of a highway passing under these rocks, the slope below these rocks was excavated and replaced with a retaining wall. However, in a heavy storm, the retaining wall collapsed and the monkey rocks slid almost two metres downslope causing fractures in the rocks. A study was made to determine the feasibility of stabilising the slope and to preserve these natural scenic rocks. During the investigation stage, boring, rock mapping and stereonets were utilised to provide maximum information of the subsurface condition and state of rock fractures. Finally, rock anchors, rock bolts, grouting, dental grouting and erosion protection were selected to stabilise the slope and the rocks. Since the stabilisation was done, the slope has weathered many storms and no further movement has been observed (a).
