The construction of the controlling engineering including adjusting stress has greatly raised the stability, and the Lianzi Cliff dangerous rock body is more stable now than ever before. In short, the effects of the controlling engineering is increasingly shown with each passing day. Through comparing such monitoring data as ground absolute displacement, relative displacement of cracks, displacement of drill depths, rock-body stress and cable tension before and after the controlling engineering, this paper deals with the effects of the controlling engineering on the deformation of Lianzi Cliff dangerous rock body and the relation between the deformation of the dangerous rock body and the construction rate as well as the construction strength.
