Landslide of Shengjibao in Fengjie County of the Three Gorges reservoir area was one of the monitoring and early-warning projects with important geographical position. Engineering geological characteristics and main influence factors were analyzed, and four monitoring methods were determined with the application of GPS in the crust deformation, deep displacement, landslide thrust monitoring. The feasibility of these monitoring methods was proved in operation, and at last, suggestions were put forward to control of Shengjibao landslide according to monitoring conclusion.
