Impact Analysis of the Yulan Avenue Bridge Underpass Construction in Close Proximity to an Operational Railway
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.
