后张T梁预应力筋管道摩阻损失测试与分析

Measurement and Analysis of Prestress' Fractional Loss of Post-tensioned T-Beam in Pipeline

通过对秦沈客运专线上跨度 16 m后张法预应力砼 T梁的预应力筋管道摩阻损失进行测试 ,验证其损失值在规范允许范围内 ,说明张拉施工满足设计及施工规范。

The measurement for prestress' fractional loss of 16m post-tensioned T-beam in pipeline on Qin-Shen Passengers' Special Railway Line demonstrates that the loss value is located within the allowed band of the standard, showing that the stretching construction can satisfy the norms of design and constraction.
