| 摘 要： | 为了了解和掌握南浦大桥结构健康状况,在南浦大桥主跨两端、主跨中央部位安装了4个GPS观测台,并组织了4次全天候连续观测,用于分析桥梁主跨昼夜变化规律、季节性变化规律。试测表明南浦大桥主跨在高程方向的变形和桥身长度变化与气温有较强的相关性。

| Abstract: | In order to find the deformation rules of Nanpu Bridge in Shanghai,continuous observations have been carried out in 4 times.4 forced centering observation stands have been installed on the bridge,2 of them on the end of bridge,the rest on the central part.The results indicate that the variations of bridge height and length were very correlated with temperature,i.e.when the temperature rises to the peak,the bridge height decreases to the bottom,while the bridge length rises to the maximum.And the daily varia... |
