description The invention relates to a method and system for determining the reasonable finished bridge state of a tandem type self-anchored suspension bridge, and the method comprises the steps: obtaining the initial vertical component force V0 of a main cable and the initial suspender force P1-Pm + n based on a main beam linear finite element model of a single tower; based on the initial vertical component force V0 of the main cable and the initial suspender force P1-Pm + n, obtaining a main cable bridge forming line shape, a main cable unstressed length and a suspender unstressed length of the single tower; based on the main cable bridging line shape, the main cable unstressed length and the suspender unstressed length of the single tower, bridging nonlinear calculation is conducted, when the main beam line shape does not meet the requirement, correction calculation of the main cable initial vertical component force V0 and the initial suspender force P1-Pm + n is conducted, and the final main cable bridging line shape
