| Abstract: | In this paper, based on the design, conception and character of the LingDing West Channel Cable-stayed Bridge with 950 m center span, we expound all kinds of factors which should be taken into account when ultra-long span cable-stayed bridge is designed, check the bearing capacity of dead and live load, dynamic load and seismic load, assess the safety of the structure, and prove the probability of constructing this kind of bridges. |
