Stemmed from Japan, for medium length spans (those between 100 meters and 200 meters),low tower cable-stayed bridge is fast becoming the bridge of choice.

Based on the design scheme of the Second Wujinag Bridge, the thesis focused on design and research of cable-stayed bridge with high and low towers by building up the integrated finite element model with MIDAS/CIVIL, a large-scale FEM software.

Analysis of slackening shake stability of a single post style diagonal cable bridge tower;

Taking an inclined-pylon cable-stayed bridge in Xiamen as an example,the article applies several cable adjusting theories to adjust the cable,and determines the completion cable force suitable for this bridge after the comparison.

The cable-stayed bridge with high and low towers and space cable plane is rare in China, the structure is novel and has its own advantages.

The cable-stayed bridge with high and low towers and single central cable plane is rare in China, its structure is original.
