Data for: Activity Law and Hydraulics Mechanism of Landslides with Different Sliding Surface and Permeability in the Three Gorges Reservoir Area, China
Description
In this paper, 670 active or deformation landslides are chosen as the research objects, and a large amount of data for the survey, monitoring and prevention are collected as follows. The reports of survey, reconnaissance or prevention of landslides. The first or second phase of survey and prevention work of geological disasters was completed before June 2003. The third phase was completed before August 2005, and the fourth phase was finished before August 2008. The data and information on landslide monitoring. The landslide monitoring system in the TGR area was built in 2002. Monitoring measurements include: (a) professional monitoring, thousands of sets of monitoring instruments and equipment have been put into operation, covering GPS (3310 monitoring piers), borehole displacement monitoring, stress monitoring, groundwater, rainfall, reservoir water level changes and etc., which carry out regular observation and collect data information about 52000 times a year; (b) mass survey and monitoring. 6098 people conduct regular ground inspections and surveys, and the information is collected 161000 times a year. The above survey and prevention, professional monitoring, mass survey and monitoring system have been in operation for more than 15 years. Every landslide in the TGR area has been closely monitored. Massive monitoring data and reports have been accumulated, thus favoring better knowledge on the characteristics, deformation law and failure mechanism of the reservoir landslide. The data range from June 2003 to December 2016, in total of 670 active landslides, were collected.
