GPS在苏通大桥索塔动态特性测试中的应用

GPS application in testing of pylon dynamic characteristics for Sutong bridge

为确保施工期桥梁索塔的安全,及时掌握施工期索塔的健康状况,避免出现灾难性后果,有必要对桥梁索塔进行动态特性测试。本文依托苏通长江公路大桥300m高索塔,并结合当时的温度和风力等自然条件对索塔的振动情况进行了动态特性分析,得出了有意结论。

The pylon of bridge must be tested on dynamic monitor its healthy situation. In this paper, combining wi characteristics in the period of construction in order to th the actual situation of 300m high pylon of Sutong bridge, some conclusions were drown out through analyzing the vibration of the pylon affected by weather, temperature and wind.
