鸭池河特大桥主塔施工监控测量与结果分析

摘要

结合贵黔高速公路鸭池河特大桥主塔的施工监控测量，阐述大型斜拉桥主塔施工监控测量与计算方法。通过对测量结果以及数据进行分析，发现主塔在施工过程中沉降量较小，不会对主塔的施工产生影响；而主塔的线型在施工过程中受温度的影响比较明显，因此在施工和测量的过程中应该充分考虑到温度变化的影响。结果表明，文中提到的方法能有效地对主塔施工进行监控测量。%The paper elaborates the construction monitoring survey and calculation method for the tower of the extra big cable‐stayed bridge based on the Guizhou highway Yachi River Bridge construction monitoring .Through the analysis of measurement results and data ,it concludes that the main tower settlement is small and serves little influence .Moreover ,the change of the temperature affects the linear of the main tower obviously ,so the effects of temperature changes will be taken into account during the construction .T he result show s that the method can effectively monitor the main tow er construction .
