| Abstract: | n light of the practice of railway ＆ highway dual-purpose Yangtze River Bridge lead project in Tianxingzhou of Wuhan, in which the variable width box girders adopt the method of full bracket cast-in-place, this paper sums up relevant construction techniques. This highway lead project crosses Daijia Lake District, which has a flushed and filled fly ash stra- tum. On the fly ash stratum, it is a breakthrough to adopt the construction technique of full bracket cast-in-plaee method. |
