以临潼某主拱跨度为72．87m的五连跨空腹式钢筋混凝土拱桥为例，建立有限元分析模型，研究其应力分布情况，确定主拱圈的应力测试方案，并对施工过程中的应力测点进行实时监测，准确把握了主拱圈的受力状况，从而确保了该桥的施工过程进展顺利，工程质量达标。%Taking the five-continuous span hollow steel concrete arch bridge with 72.87 m major arch span value in Lin-Tong as an example, the paper establishes finite element analysis model, studies the stress distribution condition, determines the stress testing scheme of main arch cir- cle, and carries out timely monitoring for the stress testing point in construction process, and correctly grasps the stress condition of the main arch circle. As a result, it ensures the smooth bridge construction and standard engineering quality.
