A finite element three-dimension space model is built by ANSYS based on the first multi-tower self-anchored suspension bridge in China. After that, the work aims at developing finite element analysis using backward and forward methods, discussing internal force of main bridge components in different construction stages. Then, linear change law of the main cable in different load conditions is analysed, and mechanism behaviour of this new structure in the whole construction is acquainted. Therefore, the work provides key force analysis for multi-tower self-anchored suspension bridge, making a good example for design and construction of similar bridges.
