摘　　要：利用Midas GTS三维有限元分析软件,对在车辆荷载作用下的施工便桥地基和供水管进行受力变形分析。结果表明:施工临时道路可采用两端以条形基础为支撑的桥跨方式跨越既有供水管。可为采用条形基础作支撑的桥跨管道工程提供借鉴。3D finite element analysis software Midas GTS was used to analyze the deformation of construction tempo⁃rary bridge base and water supply pipe under the action of vehicle load.The results of analysis demonstrate the con⁃struction temporary road is able to stretch across the existing water supply pipe with a bridge supported by strip foundation at both ends.

关 键 词：施工便桥 供水管 有限元分析
