Abstract

This paper presents a case study of slope stabilization in a constructing highway through Henan Province in China. The geology and stability back-analysis of the landslide are introduced. The more representative values of regional shear strength parameters are received from back-analysis. A solution is recommended to stabilize a 45 m high slope. This solution is to use the retaining system combining compression anchor and reinforced concrete beam. The lengths of anchors vary from 20 m to 33 m. The stability analysis of this reinforced slope is also presented. 12 monitors are installed in order to record the axial load change. Based on record data, the effect of the anchors is analyzed.
