摘　　要：由于金银台航电工程闸坝坝顶排架柱下游侧人行T型梁不能承受排架柱主梁及平台的施工荷载,施工中采用钢桁架作底部支撑。重点介绍了利用桁架浇筑排架柱主梁及平台的设计和施工,可供同类型工程参考。Because construction load of trestle main beam and platform can not be supported by footbridge T-shaped beam at downstream of dam crest trestle column at Jinyintai project, steel truss is used as bottom support. Construction design and construction of trestle main beam and platform concrete placement by using steel truss are mainly described for reference to the similar projects.
