摘　　要：以托帕水库泄洪冲沙洞(兼导流洞)故闸井闸房预应力混凝土T梁桥施工为背景,介绍了搭设支架原位现浇,并通过砂箱实现梁体落架的施工方法,最终完成桥梁施工,为类似工程提供了参考。Based on the construction of pre-stressed concrete T-beam bridge in the old gate chamber of the flood discharge and sand flushing tunnel(also as the diversion tunnel)of Tuopa reservoir,this paper introduces the construction method of erecting the support in situ and dropping the beam through the sand box and finally completes the bridge construction,which provides a reference for similar projects.
