The paper presents the “prestressed anchor cable + antislide pile” technology, analyzes the antisliding mechanisms, force bearing characteristics, design principles, design procedures and other relevant issues of the technology and makes technical and economic comparisons between “prestressed anchor cable + antislide pile” and normal antislide piles. The mentioned technology is applied in the treatment of Huangnibao landslide, which demonstrates that the “prestressed anchor cable + antislide pile” is a new generation of antislide structure with broad development future, which is featured by definite force bearing mechanisms, reasonable structure, low cost and convenient for construction.
