Abstract: With specific project example,this paper adopts rigidity support continuous beam method,force balance method,stiff hanger method and energy method to determine the rational cable force by using ANSYS software.And then,take advantage of influence matrix method to correct the stiff hanger method.In the end,point out that the method synthesizing stiff hanger method influence matrix method and constrained optimization method on the basis of energy method are more reasonable solution methods.The analysis methods can be referenced for this kind of bridge design.
