装配式预应力混凝土桥梁在老挝南椰2水电站的应用

Application of prefabricated prestressed concrete beam of bridge to construction of Nam Ngiep 2 Hydropower Project in Laos

老挝南椰2水电站厂房交通桥的梁采用后张法装配式预应力混凝土T形梁取得了成功,其优点为:保障安全、保证质量、施工速度快、工程造价低。本文重点对装配式预应力T形梁结构及施工过程作一介绍,为类似桥梁设计施工提供借鉴。

The post-tensioning prefabricated prestressed concrete T-beam is successfully applied to the construction of the access bridge for the powerhouse of Nam Ngiep 2 Hydropower Station in Laos ; of which the merits are guaranteed safety, ensured quali- ty, quick construction and lower construction cost. The structure and the construction of the post-tensioning prefabricated pres- tressed concrete T-beam are mainly introduced herein, so as to provide some references for the similar design of bridge.
