摘要
介绍大跨径曲线箱梁后张法预应力施工中,通过控制钢绞线起弯点的位置,设置防侧崩钢筋,预应力张拉前进行孔摩阻测试等确保工程安全、优质、高速的施工进程。
This paper introduces the pre-stressing construction technology of large span curved box beams in the No. 15 Bridge of Line 3 of Dalian Rapid Railway, in which smooth construction has been assured through control curving start points of steel strip, application of anti-lateral-collapsing rebar and friction test before pre-tensioning.
