摘要：An analytical method has been utilized to search for the configuration of main cables of traditional earth-anchored suspension bridges. Tan and Zhang in 2006 derived an analytical method for main cable configuration of two tower, three-span symmetrical self-anchored suspension bridges. Fewer design parameters, such as spans, sags, properties of cables, characters of stiffening girders and towers are needed in the calculation. The configuration of the main cable depends on the dead load that the main cable undergoes. The length of main cable can be obtained by the arc length integral formula. The initial and final configuration of the cable, the unstrained cable length, and saddle displacement could be obtained rapidly by solving the equations.
