Abstract: Along with gradual advance of transplantation engineering construction for Three Gorges Project, a lot of engineering slopes have been formed in the Three Gorges Reservoir Area, including soil slopes composed of residual soil, slumping mass, earth filling, swelling soil etc., and rock slopes composed of massive, stratiform and cataclastic rock. Different types of engineering slopes have different deformation and failure modes, so different measures such as drainage, flexible protecting net, shotcrete and rock bolt, lattice, retaining wall, anti-slide pile and pile-plank wall should be adopted according to their failure modes in order to assure stability of slopes and get better protection effect.
