摘　　要：将钢弦应变传感元件用于大跨度预应力混凝土梁桥施工中 ,对箱梁关键截面的应力实施跟踪测试和控制。通过对实际工程结构测试应力数据的误差分析 ,使实测应力更接近结构实际应力 。During construction of a long span prestressed concrete beam bridge, a set of stress transduers are installed at its key sections for measuring the structure strain. With the help of error analysis, the stress test results of a long span PC beam bridge are approximate to the structure stress. It is the basis that can be used to analyze the structure stress, modify the structure design and estimate the engineering quality.
