摘　　要：采用弹性磁学传感器对连云港体育馆弦支穹顶结构施工过程进行了跟踪监测,将有限元法模拟结构预应力施工过程得到的索力计算值与施工实测值进行了对比。结果表明,张拉完毕后的索力实测值与计算值比较吻合,施工方案合理,施工过程受钢结构制作、挂索和温度的影响较大。The elasto-magnetic sensor method is adopted to analyze the construction process of the suspen-dome of Lianyungang gymnasium in order to draw the variation of internal force.The simulation results from finite element analysis are compared with the measured field data,which shows that they are in good agreement after the pretension.The rationality of the construction method is also validated.The prestress construction is affected by the steel structure fabrication,the cable installation and the cable temperature significantly.
