摘要
结合国道211线灵武至甜水堡及联络线古窑子至青铜峡公路穿越大古铁路工程,根据公式进行顶力计算,并通过对框体顶进行的受力分析,找出大跨度斜交框体在顶进过程中容易失偏的原因和控制方法,以便对同类大跨度箱桥的顶力计算及顶进方向控制做出一定的借鉴。
Combined State Road 211 line the Lingwu to the Sweetwaters Fort,and contact line ancient brothel the Qingtongxia road,according to the large ancient railway engineering jacking force,and calculating according to the formula,by jacking frame stress analysis to identify the large span bias frame is easy to lose in the process of jacking partial causes and control methods,calculating and jacking directional control to make some reference to similar large span of the bridge from the top force.
