Abstract

At the two embedded solid depth, research on the displacement, bending moment and shear stress of micro-pile composite structure have been studied based on the FLAC3D program. Results show that: micro pile maximum bending moment occurs in the vicinity of the sliding surface, the maxi-mum shear stress at the position of the sliding surface about 1/8 or more, when the micro-pile composite structure designed, need to near the surface of pile are reinforced. Embedded depth and free segment length ratio of 1:3, the displacement, shear stress and bending moment of micro-piles are relatively small, micro-pile composite structure can bear greater landslide thrust. micro-pile composite structure in the governance of sliding bed for bedrock and soil landslides, the main fail-ure mode is near the sliding surface of the pile when bending and shearing failure occurs.
