Case study of slope stabilization using compression anchor and reinforced concrete beam

This paper presents a case study of rock slope reinforcement in a constructing highway through Henan Province in China. The soil strength parameters are obtained by the back stability analysis of a 26.7 m high landslide. A reinforcement system combining compression anchor and concrete beam is used to stabilize the slope with 45 m in height near the landslide. 12 monitors are installed in order to record the change of axial force of the selected anchors. The monitoring data shows that the axial forces of the selected anchors are all under design load. It is concluded that the reinforcement system is effective for stabilizing the slope in the landslide area.
