南水北调穿公路埋地输水管道的结构计算研究

Research on Structural Calculation of Road Crossing Buried Water Conveyance Pipeline ofthe South-to- North Water Diversion Project

南水北调供水项目沿线穿越公路工程众多,输水管道结构稳定性对输水工程的整体安全有着较大的影响。文章以河南省某南水北调配套工程为研究对象,详细介绍了穿越公路段埋地输水管道的结构计算方法。通过分析管道受力,计算其强度、稳定性,校核管道抗震性能,验证穿越段管道的强度及稳定性均满足设计要求,为此类穿越工程输水管道的结构计算提供参考,便于工程应用。

There are many road crossing water supply pipelines of the South-to-North Water Diversion Project,and the structural stability of the water supply pipeline has a great impact on the overall safety of the water conveyance project.In the paper a water supply system of the South-to-North Water Diversion Project in Henan is taken as the research object,explaining the structural calculation method in detail.Based on the analysis of the load of pipeline,the strength and stability of the pipeline is calculated,the seismic resistant property of the pipeline is checked.It is verified that the strength and stability of the buried water pipeline meet the design requirements,that could be used as reference for the structural calculation of similar water conveyance system.
