| Abstract: | As the segments of the steel tube arch ribs of huge-span concrete-filled steel tub arch bridges increase, the cantilever is lengthened. The external environment temperature change has a more apparent influence on the arch rib alignment, which brings many difficulties to the alignment control. The paper introduces the analysis and relative installation countermeasures of the influence of temperature load on the arch rib alignment. |
