Failure of rock or soil slopes takes place due to natural or artificial means. Natural events include failure due to flash flood, excessive seepage, pore pressure, seismic event, presence of weak discontinuities across the rock slope, shear zones, toe cutting of slope by meandering river leading to unstable slope due to change in slope geometry.…
Ground Anchors are the structural members that are installed deep into the rock mass with their main applicability to transfer the applied tension load deep into ground/rock mass. Sometimes, also referred to as tieback anchors. The main component of the ground tieback anchor is shown in figure 1. The anchorage is the combined system of…
