It is crucial to ensure the structural safety of buried steel pipes(BSP)as they are increasingly utilized in major water diversion projects,as the lifeline of these projects.However,current BSP structural calculation methods lack the consideration of pipe's self-weight.In view of this,we developed a calculation method considering the self-weight of pipes based on the Spangler model theory,and compared the results with those of traditional and finite el-ement methods.Results demonstrate that the proposed calculation method merely integrates the ...
