Abstract
The mechanical characteristics of steel pipe crossing structures for transmission lines have a significant impact on the safety and reliability of crossing construction,with the aim of optimizing the design and construc-tion scheme of crossing structures.Taking a practical project as an example,ANSYS software is used to pa-rameterize the modeling of steel pipe crossing frames,wind loads on the crossing frames are calculated and ap-plied,and the influence of the structure of the crossing frames on their mechanical properties is analyzed.The results indicate that as the spacing between the poles increases,the maximum stress of the crossing structure and the tension of the cable gradually decrease,and the buckling factor shows a decreasing trend.The variation of the horizontal bar spacing has little effect on the maximum stress and tension of the tension wire,and the buckling factor shows a nonlinear increase as it increases.The change in spacing has a relatively small impact on the maximum stress of the crossing structure,but the tension of the cable decreases nonlinearly with the in-crease of spacing,and the buckling factor of the crossing structure changes nonlinearly with the change of spac-ing.It is recommended that in practical engineering,the spacing between the uprights and the step distance of the crossbars of the crossing structure should be controlled between 1.5 m and 2 m,and the row spacing should be controlled between 2 m and 3 m to ensure the stability and safety of the structure.关键词
