摘　　要：以桐岳高速六标波纹管人行通道为工程背景,采用有限元数值模拟的方法,分析不同壁厚(5 mm,6 mm,7 mm,8 mm,9 mm)条件下拱形波纹钢涵洞受力及变形的特征。结果表明:壁厚的增加会整体降低管涵的应力;壁厚的增加对管涵侧面的应力变化控制效果要好于管涵顶部和底部区域;壁厚的增加可以减小波纹钢管涵的变形,当壁厚增加至一定的值时,减小的变形量较小;若仅考虑壁厚对结构的受力及变形这一影响因素,本工程中波纹钢管涵的较佳壁厚选择为7 mm。Taking the six-standard corrugated pipe pedestrian passage of Tongyue Expressway as the engineering background,the force and deformation characteristics of arched corrugated steel culvert under different wall thicknesses(5 mm,6 mm,7 mm,8 mm,9 mm)were analyzed by finite element numerical simulation method.The results show that the increase of wall thickness will reduce the stress of the pipe culvert as a whole.The increase of wall thickness has a better effect on the stress change control effect on the side of the culvert than that at the top and bottom of the culvert.The increase of wall thickness can reduce the deformation of corrugated steel pipe culvert,and when the wall thickness increases to a certain value,the reduced deformation is small;if only the influencing factor of wall thickness on the force and deformation of the structure is considered,the best wall thickness of the corrugated steel culvert in this project is 7 mm.
