The invention discloses a pile body bending moment calculation method. The pile body bending moment calculation method is characterized by including the following steps: one to three strainometer positions are selected from a pile body to serve as standard sections, the bending moments M of the standard sections under the effect of all-level horizontal test loads H are calculated respectively, and the relation function M (delta epsilon) between the bending moments M of the standard sections and the corresponding bending strain delta epsilon is built; the actually-measured bending strain delta epsilon of the crosses is substituted into the relation function M (delta epsilon), and the bending moments M of the corresponding actually-measured crosses are calculated. The pile body bending moment calculation method has the advantages that testing data are sufficiently used for calculation, calculation errors caused by nondeterminacy of the pile body concrete elasticity modulus E can be avoided, the calculation method is easy and convenient, errors are small, and the accuracy is high.
