| Abstract: | Based on the construction of the Huluhe Extra Large Bridge of Huangyan Highway, this paper gives a brief introduction of the side-span cast-in-place technique. By changing the sequence of beam - folding in time, shortening the length of the cast - in - place beam of the side-span, combining the construction methods of unbalanced cantilever beam casting and bracket casting-in-place, the difficult problems of the construction of high and large side-span is successfully solved, which may provide instructive reference for other similar works. |
