斜塔无背索斜拉桥病害分析及加固方法

Disease Analysis and Reinforcement Method of Leaning-pylon No-backstay Cable-stayed Bridge

无背索斜拉桥是由传统斜拉桥发展而来的一种结构形式,为研究无背索独塔斜拉桥的病害形成机理,以某无背索独塔斜拉桥作为工程案例,结合该桥多年的检测报告结果和该类型桥梁的受力特点,对该桥的病害产生原因进行了分析,同时针对具体的病害类型给出了应采用的加固方法。

In order to study the disease formation mechanism, taking a no-backstay single-pylon cable-stayed bridge as an engineering case, and combined with the detection report results of bridge for many years and the stress characteristics of this kind of bridge, this paper analyzes the disease forming causes of this bridge, and gives the reinforcement methods for the type of diseases in detail.
