Use of Shallow Anchors and Anchored Mesh System for Cut Slope Protection in Ice-Rich Soils

The overall objective of this research is to investigate the performance of shallow anchors in frozen soils and develop an anchored wire mesh system which can be used to solve the problems associated with the exposed ice-rich permafrost cut slopes. The system will be safe, environmentally acceptable, cost-effective, and requires little maintenance in the long term. The specific goals of the project are as follows: (1) Investigate the rate of thermal degradation of ice-rich permafrost cut slopes. (2) Investigate load transfer characteristics of a shallow anchors during freeze-thaw cycles. (3) Investigate the local and global stability of the slope protection systems. (4) Investigate performances of different anchored systems for ice-rich permafrost cut slopes exposed during construction and investigate the optimum design for ice-rich permafrost cut slopes. (5) Investigate methods to construct ice-rich permafrost cut slopes with an anchored slope protection system. The results will be used to develop design and construction guidance for anchored slope protection systems for a variety of field conditions in Alaska.
