The Yulan Avenue bridge of the project of river diversion to Huaihuai passes through the existing He'an high-speed railway Feixi liaison line between piers #43 and #44 of Fangxing Avenue Special Bridge.MIDAS GTS NX finite element software is used to establish a model to analyze the impact of the road bridge close to crossing the high-speed railway during the construction stage as well as the operation stage of the railroad and bridge structure.The results show that:the displacement of railroad piers is within 1 mm,which meets the relevant requirements of the industry;the monitoring results of the construction site are slightly lower than the theoretical calculation value,indicating that the underpassing program is reasonable and feasible.
