本文利用应变计实测数据,对山西中南部铁路通道跨京沪高速公路特大桥连续梁进行应力监测计算,在数据处理中采取阶段扣除应变法,较好的解决了非弹性应变难以准确扣除的难题。 In this paper, strain gauges are used to calculate the stress of continuous beams of railway bridges across the Beijing-Shanghai Expressway in central-southern Shanxi Province. The phase-deduction strain method is adopted in the data processing to better solve the problem that the inelastic strain can not be accurately deducted .
