What works can be done when landslide of slope occurs?

The following short paragraph has been found, which is written by a mainland associate professor (some words have been edited), hope that helps:

... the basic principle, the design method and the effects of remedy for deep-strata landslide disaster are introduced in tiffs paper by stabilizing piles with prestressed anchor ropes, one end of the anchor rope is iframeded in stable rock mass, while the other is connected to the head of the stabilizing pile, and then the anchor rope is prestressed. The stabilizing pile, one end of which is fixed and the other is free, is changed from one state of free head into another statee of elastically fixed head,so that the landslide disaster is remedied. In recent years, the author has used tiffs method for remedying more than thirty landslides, and all of those have received very well significant effects. This method can generally saved a cost of 20%～40% for the deep-strata landslide of highway.
