新形势下火电企业电煤管理问题与对策研究

聊城市湖南路大桥是一座无背索斜塔竖琴式斜拉桥。主梁采用超宽预应力混凝土结构，建成后宽幅将居同类桥型之首。无背索斜塔斜拉桥最大的特点是利用倾斜索塔的自重而不是背索索力来平衡主跨主梁的自重。介绍了湖南路大桥的主要设计特点及主体结构的施工方法，并对设计中遇到的一些关键性问题进行较系统的研究，有利于该桥型的进一步发展。

The Hunan Road Bridge in LiaoCheng City is a harp type cable stayed bridge without backstays. The main beam is prestressed concrete structure which will be the widest bridge of similar type in China. The specialty of this style bridge is that the dead weight of inclined pylon is substituted for the back stays force to counteract the girder dead weight of main span. This article describes the main design features of the Hunan Road Bridge and the construction of the main structure, and systematic researches for some crucial problems in its design, which will be helpful to the further development of this bridge type.
