长江三峡危岩体防治两大主体工程——“五万方”“七千方”锚索工程和T8—T12缝段承重阻滑键工程于1995年5月开工，分别于1997年8月、1999年8月竣工。崩滑地质灾害防治工程是风险很大的工程，工程施工对危岩体，特别是对其中局部敏感部位的影响是难以完全避免的，受扰动的危岩体适应应力调整产生相应的变形是一种正常现象，但扰动过大，可能会导致危岩体失控，产生严重的不良后果。\n
在防治工程施工过程中，同步监测危岩体的变形动态，分析判断危岩体的稳定性及其变形趋势，做出超前预报；及时捕捉重大变形信息和突发险情的征兆，供业主和施工单位决策相应防范应急措施。\n

T12 seam section load-bearing slip resistance key project started in May 1995, respectively in August 1997, August 1999 completion. Avalanche slip geological disaster prevention and control project is a risky project, engineering construction on the dangerous rock body, especially on the local sensitive parts of the impact is difficult to avoid, the disturbance of the dangerous rock body to adapt to the stress adjustment to produce the corresponding deformation is a normal phenomenon, but the disturbance is too large, may lead to the dangerous rock body out of control, resulting in serious adverse consequences.\n
In the prevention and control of the construction process, synchronized monitoring of the deformation of the critical rock body dynamics, analysis and judgment of the stability of the critical rock body and its deformation trend, to make ahead of the forecast; timely capture of major deformation information and signs of sudden danger, for owners and construction units to make decisions on the corresponding preventive and emergency measures.\n
This dataset includes the monitoring dataset of engineering prevention and control effect. The data format is csv format, and the observation cycle is once a month.
