| 摘 要： | 通过有限元分析预制T梁在不同欠张拉状态下的受力性能,确定预应力结构处于安全状态时临界值;通过足尺寸（25 m）T梁试验,分析其在荷载作用下的应变和挠度,通过实测值与理论值的比较,表明结构处于安全状态时临界值的可靠性;比较临界值与锚下有效预应力取值合理范围,得出锚下有效预应力安全性富余度。

| Abstract: | The loaded capacity of the precast T beam was analysed by means of finite element method in the different less tension situation,then the.The critical value in the safety was drawn.Under the action of load,strain and deflection of the measured value and the theoretical value were compared with carrying out load experiments with the sufficient size（25 m long） T beam test,and the critical value in the safety was testifyed reliably.With the critical value compared to the reasonable numerical value range of the effective prestress under anchou,the safety surplus of the valid prestressed force under anchor was drawn. |
