摘要
对预应力锚下结构的应力进行了比较详细的数值分析 ,根据锚下应力分布的特点 ,确定 STM锚下结构的形式和主要结构的尺寸。和国内同类锚具的锚下结构相比 ,STM锚具有结构合理、使用安全、整体重量较轻的特点 ,从而产生很好的社会和经济效益。
The stress of the end block under the prestressed anchorage was analyzed by a numerical method, its results were used to design the structure under STM anchorage, which is named base plate. The base plate designed is safer, lighter than the one, which is widely used in prestressed concrete structure in our country. The considerable economic and social benefits will be achieved by use of STM anchorage.
