The invention discloses a load resistance subitem coefficient calculation method, a storage medium and equipment, and belongs to the field of ballastless tracks, a structure limit state function is established and simplified, an equivalent resistance attenuation coefficient g * is introduced, an empirical calculation formula of the g * can be obtained by utilizing calculation and simplification of the equivalent resistance attenuation coefficient, and on the basis, the load resistance subitem coefficient is calculated. By introducing a three-order moment reliability theory, parameters such as muR0, sigmaG0, alpha3G0, beta2T0, muRT, sigmaG, alpha3G and beta2T can be quickly obtained, a load and resistance subitem coefficient calculation formula considering resistance performance degradation of the whole life cycle structure is accurately constructed, and a load resistance analysis coefficient is quickly obtained. The method is simple, operation is easy and convenient, the structural resistance ...
