| Abstract: | According to the structure characteristics of Tanana River Bridge in Alaska of America, this paper introduces a kind of method of making holes for the bolted and welded structure with ballast pan connected with top flanges of main girders by bolts, to ensure alignment of holes, decrease erection difficulty, and improve production efficiency. Through practice, the fabrication quality of the members for the bridge meets the requirements of contract and code. hence the alignment of bolts is good enough to make the smooth erection, the method is proved to be scientific and reasonahle. |
