Calculation method for conversion coefficient between bearing capacity and calculation length of high pier

The invention discloses a calculation method for a high pier bearing capacity and a calculation length conversion coefficient, belongs to the technical field of civil engineering structure analysis and design, mainly aims at high pier design of infrastructures such as roads and bridges, and aims at accurately evaluating the performance of a high pier structure by combining a finite element model and a theoretical model. The method comprises the following steps that firstly, a finite element model is used for conducting structural simulation of a high pier, and a load-displacement curve is generated to evaluate the response of the high pier under the actual load; secondly, determining a calculation length conversion coefficient of the high pier by applying a theoretical model, and considering an axial force distribution effect of the high pier and a nonlinear behavior of a material at the same time; further, calculating a stiffness damage ratio by combining data obtained by using the finite element model and t
