| 摘 要： | 基柱内力的计算分析是输电铁塔下部基础设计一个重要的环节。基于刚性桩和弹性桩不同的受力和变形特征,本文简要阐述了水平受荷桩的计算理论,分别探讨了上述两类桩内力的计算分析方法,并重点对刚性基柱考虑土抗力时内力的计算公式进行了重新推导,发现规范中给出的相应计算表达式存在一定的不合理,从而得到更正的计算公式,这一公式目前已应用于架空输电线路基础设计技术导则中。

| Abstract: | The calculation of pillar internal force is some important section in designing the underlying base of transmission tower.The analytic principle and methods for the internal force of the laterally loaded pile are briefly proposed based on the different states of forces and displacements of rigid pile and elastic stabilizing pile.This paper derived the formula for the rigid pillar considering the soil frictional resistance.And this derived formula is different with that of the national code,which is used to ... |
