摘要
Abstract
Yu-Qian Railroad is an important part of Baotou-Liuzhou Railway in the railway main lines.In order to ensure the quality and safety of the x-type arch bridge which is going to be built in Yu-Qian Railroad.The calculation and analysis are made of the stress of the main arch ring,the stability of the operation phase and the displacement by Midas/Civil2010 FEM software.The results indicate that the maximum stress of arch springing is 14 Mpa which can meet code requirements.K is 32.2 which can meet the present code in the operational stage.The natural vibration period of transverse and longitudinal directions are 1.473 s and 1.389 s which can meet code requirements.关键词
