The invention discloses a combined loaded pile bearing capacity transfer matrix general solution method. The method comprises the following steps that a combined loaded pile general solution stress analysis model is built, and a general expression convenient for finding pile-soil interaction relation during the general solution is provided; according to the one-dimensional linear characteristics of a transfer matrix, discretization, uniformization and constant processing are conducted on the soil resistance coefficient, the distribution of axial force of a pile and horizontal load distribution of the pile; analytical general solutions of the transfer matrix coefficient of a free section of the pile, the transfer matrix coefficient of a flexible section of the pile and the transfer matrix coefficient of a plasticity section of the pile are obtained by means of the Laplace direct-inverse transform derivation; based on the principle of the transfer matrix method, boundary conditions of the pile top and the pile end are substituted, and accordingly the combined loaded pile bearing capacity general solution is obtained. In the method, the analytical expression of the transfer matrix coefficients is very simple, programming calculation is convenient, the method is very good in adaptability and universality, and the problem of combined loaded pile bearing characteristics under various working conditions in the geotechnical engineering can be well solved.
