摘　　要：由于占地面积少,单桩基础单管通信塔得到了广泛使用。钢结构单管通信塔采用单桩基础时,计算桩身内力和桩顶位移的方法较多。论文结合规范推荐的m法,分析了单桩基础水平承载力的影响因素,包括截面刚度、桩顶约束形式、桩侧地基土水平抗力系数的比例系数取值和桩长等,并参照分析结果和其他行业规范,对各影响因素在设计时的合理取值提出建议。Single-pipe telecommunication tower is wildly used because of saving land. In the designing of single pile foundation, there are several methods to compute the internal forces of pile and the displacement of pile top. Based on the m method recommended by the Standard, the influence factors are analyzed, including stiffness of cross section, constraints of pile top, proportional coefficient of the horizontal resistance coefficient of foundation soils and length of pile. And based on the analysis, rational values of the factors in designing are recommended.
