本文论述的是一特大桥在现场施工中遇到的施工应用实例。因受地形及附近路基成形限制导致按常规工艺无法按期完成，故经过研究形成了在无预制场情况下T梁预制及安装的成功应用实例。实例中详述了预制台座施工、吊架安全作业、预应力张拉伸长量等的控制对策，对相关深山峡谷地域的桥梁预制施工有较强的指导意义。

this paper discusses the construction of a bridge at the scene encountered in construction applications. Due to topography and forming limit of subgrade induced by conventional process can not be completed, after researching the formation in the absence of precast t-beam precasting and installation of instance of successful application. Instance precast pedestal construction, and hangers are detailed in security operations, prestressed stretching elongation control strategies, geographical bridge prefabrication of the mountains Gorge has a strong significance.
