针对斜拉桥塔梁同步施工时主塔的线形控制和索道管测量定位等测量技术进行研究与分析,精确测量并计算出塔梁同步施工产生的不均匀水平力使主塔位置产生的偏移量。然后在主塔测量控制和索道管高精度定位测量中进行修正处理,通过测量误差分析和精度计算的方法,保证斜拉桥塔梁同步施工时塔柱的线形和索道管测量定位的精度。
In order to analyze and measure the linear control of the main tower and the measuring and positioning of the cable duct during the simultaneous construction of the cable-stayed bridge, accurate measurement and calculation of the uneven horizontal force caused by the simultaneous construction of the tower so that the position of the main tower is offset the amount. Then, the correction measures are taken in the measurement and control of the main tower and the high-precision positioning and measurement of the cable duct. The method of measurement error analysis and accuracy calculation is adopted to ensure the accuracy of the tower profile and cable duct measurement and positioning during the simultaneous construction of the cable-stayed bridge.
