【Abstract】 In the preliminary design of Taizhou Changjiang River Highway Bridge,the proposed structural type of a three-tower suspension bridge with two main spans(2×1 080 m) was recommended for the main bridge of the Bridge.Using the finite element model,this paper investigated the impact of several key design parameters,such as the rise-to-span ratio,intermediate tower height,stiffening girder depth and supporting systems,of the three-tower suspension bridge on the structrual behavior of the bridge and the results of the investigation were already adopted in the preliminary design of the Bridge.更多还原
