The deformation characteristics analysis of scattered insequent landslide reinforced by prestressed anchor cables

Research purposes: A large number of mountainous highways under constuction and that is already built involve cutting slope engineering problems. Through monitoring of deep horizontal displacement and surface displacement, the exact position of the slide surface was found, analyzing the whole deformation process scattered on the body and turn into landslide without retaining after slope excavation, to provide a basis for emergency design of landslide. Through analyzing the amount of deformation observation data of scattered insequent landslide, the landslide displacement characteristics before and after rock reinforcement were obtained. Research conclusions:(1) The deformation characteristics of the scattered insequent landslide are scattered in front, slip in after, the landslides are generally converted by scattered together. Landslide attaches scattered body and the slide zone part attaches to scattered zone. (2) Through monitoring data, the exact position of the slide surface was found, the whole displacement development and changes of scattered landslide were monitored and truly described. (3) The landslide retaining arrangement prestressed anchor can take the initiative to protect the slope and play a significant reinforcing effect to broken rock and landslide deformation. (4) The research result can provide a basis to landslide emergency design and win the time for the landslide protection, and provide reference and empirical criteria for the construction and design of this kind of slope. © 2016, Editorial Department of Journal of Railway Engineering Society.
