Construction method of soil-rock aggregate foundation pile foundation horizontal soil resistance-displacement skeleton curve model suitable for different seismic oscillation intensities

The invention provides a construction method of a pile foundation horizontal soil resistance-displacement skeleton curve model of an earth-rock aggregate foundation suitable for different seismic oscillation intensities. The pile foundation horizontal soil resistance-displacement skeleton curve model of the earth-rock aggregate foundation adopts a Davidenkov function; the influence of soil-rock mixture foundation modulus degradation caused by the earthquake load on the pile-soil interaction characteristic is considered; two types of failure modes of a shallow wedge body and a deep streaming of the soil-rock mixture around the pile are reflected; the extreme soil resistance around the pile when the wedge body is damaged is exported by a wedge body damage mode, a pile-soil interaction mechanical model, a wedge-shaped soil body geometrical relationship and a static balance condition; the pile periphery limit soil resistance during streaming failure is exported by a streaming failure mode, a pile-soil interaction
