摘要
简要介绍了桥梁结构局部承压的受力特点、破坏形式和破坏机理,及局部承压的计算方法,并通过沈阳绕城高速公路项目中的工程实例,分析验算了后张法预应力钢束的局部承压承载能力。
The loading features, failure mode and failure mechanism of local bearing of bridge structure are introduced briefly, the calculation method for local bearing is introduced, and the analysis and checking calculation on local bearing capacity of prestressed steel strand are made by using post - tensioning method based on the project case in Shenyang belt freeway project.
