AbstractThe composite structure of row posture micro-piles is a light-weight protection structure for slope, which has the advantages of safe and quick construction, high adaptability to some special environment, and is suited to small size slope protection, especially in the emergency project. The design theory research of this composite structure is obviously deficient comparing to the engineering application. The basic requirement of the elastic foundation-beam theory application is that the foundation should be stable. Because of the row posture micro-piles composite structure improved the stability of slope, the resistant force in front of different location micro-piles is different. On the basis of the elastic foundation-beam theory, using the idea of the general micro-piles horizontal bearing capacity calculation method, the row posture micro-piles advantage have been revealed during the different calculated values of "m" and limited conditions of pile top large deformation. The computational formula of row posture micro-piles composite structure has been established on three basic calculation models, and the special response to seismic force has been calculated and analyzed in a practical case, which will provide certain reference for the micro-piles design.
