| 摘 要： | 长江三峡链子崖危岩体防治工程的实施，使其安全度有了较大提高，经过应力调整，已使其变形趋于稳定，防治工程效果日渐显著。通过对链子崖危岩体防治工程进行前以及施工过程中的地表绝对位移、裂缝相对位移、钻孔深部位移、岩体应力和锚索张拉力等监测资料的分析对比，讨论防治工程施工对链子崖危岩体变形的影响，论述施工进度、施工强度与危岩体变形的对应关系。

| Abstract: | 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. |
