合蚌客专350km/h单线试验箱梁工艺试验研究

Study on Process Test for Box Girder of Hefei-Bengbu Dedicated Passenger Railway 350 km/h Single-Track Line

时速350公里客运专线单线后张法单箱单室预应力混凝土简支箱梁属首次应用。为验证其各项指标,进行了4孔箱梁的试验工作;通过对箱梁的各项工艺试验进行研究,充分验证箱梁的设计。

The post-tensioning method single-cell pre-stressed concrete simple box girder for 350 km/h dedicated passenger railway single-track line is used for the first time.To verify its performance indexes,four-truss box girder test is carried out,studies on box girder process tests fully verify the design of box girder.
