Aiming at the consolidation problem of concrete-cored sand-gravel pile composite foundation considering temperature effect and nonuniform distribution of initial pore pressure,the calculation model of concrete-cored sand-gravel pile composite is established,the general solution of consolidation of concrete-cored sand-gravel pile composite foundation considering temperature effect and nonuniform distribution of initial pore pressure by analytical method. The correctness and rationality of this solution are verified by degradation study and comparison with existing solutions. According to the analytical solution of this paper, the calculation program is compiled, and the consolidation of concrete-cored sand-gravel pile composite foundation is obtained considering the temperature effect and the nonuniform distribution of initial pore pressure.The results show that the higher the temperature is, the faster the consolidation rate is, but the influence of temperature change on consolidation is gradually weakened;under the influence of the same temperature, the initial pore pressure is faster to consolidate in a trapezoidal distribution than in a rectangular distribution, fastest to consolidate in inverted triangular distribution and slowest to consolidate in a positive triangular distribution.
