• Abstract:
  Instability of erodible slopes due to extreme climate events and of permafrost slopes due degradation and thawing is a significant ; engineering problem for northern transportation infrastructure. Engineers continually look for mitigation alternatives to stabilize ; erodible slopes and reduce thaw instability and related hazards in permafrost areas. Traditional stabilization techniques tend to be costly ; as they require specialized skills and equipment to ensure adequate performance. Additionally, the effectiveness of traditional slope ; stabilization methods becomes limited in cold climatic conditions. Recently, geofibers and synthetic fluid have been used to improve ; very loose sandy soils. The projects propose is to conduct a large-scale field investigation to study the feasibility of stabilizing erodible ; and thawing permafrost slopes with geofibers and synthetic fluid. The proposed research will greatly help minimize the problems and ; risks posed by thawing permafrost slopes instability in cold regions. The outcome of this research will be useful in ensuring a reliable, ; safe and economic design. The followings are expected to be accomplished: (1) large-scale testing of the proposed technology on an insitu ; slope, 2) development of design guidelines for producing plans and specifications for geofiber/synthetic fluid reinforced slopes, 3) a ; guidance manual for construction installation and maintenance of the constructed slope
