| 摘 要： | 在运营状态,采用环境激励测试拉索振动加速度响应,对新八一大桥的所有斜拉索进行了内力测试,为大桥的安全使用提供了可靠的依据,也为同类桥梁的斜拉索内力测试提供参考。对大桥的测试结果表明拉索内力有一定的变化,但仍在安全范围之内。

| Abstract: | The internal forces of all stay cables of the New Bayi Bridge were inspected and tested in the operation state of the Bridge through measurement of stay cable vibration acceleration with environment excitation method.The inspection and tests provide reliable basis for safety operation of the Bridge as well as reference for the stay cable internal force tests for other similar bridges.The results of the tests indicate that the operation of the stay cables of the Bridge is still within safety range though there are some changes of the internal forces in the stay cables. |
