摘要
结合某超高输电塔的工程实践,从设计角度出发,采用非线性有限元方法分析了特大荷载作用下输电塔基础关键节点的受力特征及混凝土裂缝开展规律,根据计算结果对高塔基础设计方案进行了优化。采用的方法和所得结论可为类似工程提供参考。
According to a typical extra-high transmission tower project,the mechanical behavior of key nodes and the development of concrete crack for transmission tower foundation were investigated in detail using the nonlinear finite element method（FEM）.The design was optimized based on the computed results.The method used and the conclusion reached in this study will be useful for similar engineering projects.
