| 摘 要： | 以我国公路中常用的40m箱梁桥为原型，按照强度等效原理作了一片缩尺体外预应力混凝土粱，并对其做了三分点加载的破坏试验。利用有限元建模分析对试验结果进行了预测。从试验数据的分析中得出了有关体外预应力试验梁的一些初步结论。

| Abstract: | A reduced scale externally prestressed concrete beam is loaded to failure under third-point loading, which is made by the theory of equivalent intensity. The prototype is a box girder with 40 meters length, which is widely used in highways of China. The results of finite element analysis are used to predict the course of the test. Some conclusions have drawed from the analysis of the experiment. |
