摘要
结合PC斜拉桥结构及施工特点,提出了其主梁应力应变的测试技术和分析方法,对混凝土应变传感仪器的选择、测点布置、影响因素分析、实测值的计算与修正进行了研究,并在PC斜拉桥施工和营运中进行应用,取得良好效果。
With reference to the structure and construction features of prestressed concrete （PC） cable-stayed bridges, this paper presents the measurement techniques and analysis methods for stress and strain of main girders of the bridges, and also conducts researches in relation to the selection of strain gauges for concrete structures, strain measurement point layout, influential factor analysis, calculation and modification of field measurement values. The techniques and analysis methods herewith prove to be quite effective through their applications to the PC cablestayed bridges being constructed and/or have been put in service.
