摘　　要：针对剑江特大桥施工监控中采用的振弦式应变计测量应变,通过合理确定测点位置以及测试时间,对应力测试中的影响因素进行了讨论,并对主要影响因素进行了修正,从而使测量应力较客观的反映结构应力的真实状态。In light of vibrating string extensometer used to measure strain in Jianjiang extra large Bridge construction monitoring, through reasonable determination on testing point position and testing time, it discusses influential factors in stress test, and modifies main influential factors, so as to make stress measured can rather objectively reflect real state of structure stress.

关 键 词：施工监控 振弦式应变计 应力测试
