The two main projects of the Three Gorges of the Yangtze River for the prevention and control of dangerous rock bodies - “50,000 square meters”, “7,000 square meters” anchor cable project and T8-T12 seam section load-bearing anti-slip key project was started in May 1995 and completed in August 1997 and August 1999 respectively. 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.

  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.

  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. Data fields include: STARTDATE (collection start time), ENDDATE (collection end time), quduan (zone), pointname (point name), x (x-direction horizontal displacement variable, unit: millimeter), y (y-direction horizontal displacement variable, unit: millimeter), f (horizontal displacement variable, unit: millimeter), direction ( Direction of deformation, in degrees), yblx (x-direction horizontal displacement monthly variable, in millimeters), ybly (y-direction horizontal displacement monthly variable, in millimeters), yblf (horizontal displacement monthly variable, in millimeters), direction1 (deformation direction monthly variable, in degrees), and location (monitoring point location).
