| 摘 要： | 通过对某一高墩大跨连续刚构桥悬臂施工过程各阶段的控制截面进行理论分析与应力测试，找出了施工过程中该桥受力控制截面的应力变化规律，得出了有益的结论：可以用钢弦式应变计来监测梁体的应力变化，随着悬臂施工的进行其根部压应变越来越大等，可以为该类型桥梁的施工与设计提供参考。 |

| Abstract: | A stress test and theoretical analysis made of a large-span,rigid-framed continuous bridge with high piers during the cantilevering construction in the paper,through which some laws of the stress changes in critical sections are found and obtained are some conclusions that the laws of stress changes can be tested by means of embedded vibrating wire strain gauge and the compression strain in the bridge' 0# box gets greater and greater with the progress of the cantilever construction.The paper may serve as a ... |
