PRELIMINARY STUDY OF THE SLIP MECHANISM AND THE STOPING METHOD ON THE LANDSLIDE OF THE APPROXIMATELY HORIZONTAL EXCAVATED SLOPE IN RED BEDS

This paper introduces a concept of the approximately horizontal terrain based on Songjiapo landslide along the Guangnan expressway. The authors analyze the slip mechanism and recommend stopping method on the landslide of the approximately horizontal slope in red beds. The concept and method presented in this paper provide a good example and guidelines for investigation, design and construction of other similar work.
