years of safety monitoring for the landslide of Hancheng PowerStation
2008
Hancheng PowerStation was completed in November 1979. However, lots of cracks began to appear on the east side of the mountain, large area of the station was uplifted, and the powerstation and appurtenant structures were seriously damaged in 1982. With the installed capacity of 380 M watts, Hancheng PowerStation is about 4 km from the northwest of Hancheng City, Shanxi Province. The landslide was controlled in some way after the treatment in 1985. However, the deformation speeds at various monitoring points were suddenly increased greatly after May 1994. Safety monitoring of Hancheng PowerStation has been started from 1982 during the ground deformation monitoring. Hancheng PowerStation is located at the grade II terrace of Jushui River and the eluvial zone of the mountain front slope. With Hengshan Mountain on the east and Jushui River on the west, the landform is slightly inclined from east to west.
