For high-slope retaining structures buried in the shallow rock,based on the load structure method,the model was reasonably simplified according to the theory of elastic foundation beam.The anti-skid pile foundation will be optimized from the distributed structure to the double-row pile revetment structure,which can play fully the role of end-fixing of raw-pile in the rock section,reduce the pile internal force and deformation,and reduce the interference with neighboring buildings,so as to reduce the construction difficulty of the pile into the rock.
