| 摘 要： | 结合徐洪河大桥施工控制工作,通过数值模拟与实测,对在地面拼装的三角挂篮进行对拉预压试验,并研究试验与实际施工时挂篮结构受力、变形间的差异,为合理确定箱梁悬臂浇筑中挂篮变形值提供依据.试验所得数据经过差异分析和处理后可用于预拱度计算.

| Abstract: | In combination with control in construction of Xuhonghe Bridge and based on numerical simulation and actual measurement,this paper carries out the test for counter tension pre-pressure of triangle hanging baskets assembled on the ground,and studies difference between load on structure of hanging basket and deformation in test and actual construction to provide bases for determining deformation values of hanging baskets in pouring of cantilevers of box girders in a reasonable way.The data obtained in the test after difference analysis and treatment can be used for calculation of precamber. |
