摘要
通过太中银铁路中宁黄河特大桥、永宁黄河特大桥主桥钢桁梁在冬期负温条件下拼装时对高强度螺栓扭矩值的试验数据统计分析,探讨了钢桁梁冬施拼装中在负温下采用的调整扭矩系数经验值。
According to analyze the empirical datum of high intensity bolt torque value in assembling steel truss beam in winter time construction, negative temperature condition of Zhongning Yellow river big Bridge and Yongning Yellow river big Bridge in Tai-Yin railway, it discusses regulating torque modules empirical value that steel truss beam adopting in winter time construction assembling under negative temperature.
