一座铁路预应力混凝土平弯桥——南昆铁路板其二号大桥

A Horizontally Curved Beam Bridge—Banqi No.2 Bridge on Nanning Kunming Railway Line

提出了平弯梁桥的应用，对加大铁路选线自由度的重要性，对试点的板其２号大桥作了简单介绍，并讨论了平弯桥应考虑的一些问题，从而得出平弯桥有它广泛应用前景的结论。

It is argued that the application of curved beam bridges will play an important role in increasing the freedom of selecting railway alignment. A brief introduction is made of Ban Qi No.2 Bridge as an experimental one. Some problems which ought to be considered in bridges curved in horizontal plane are studied. Conclusion is drawn that such kind bridges will have a wide application in the future.
