输电线路杆塔钢管插入式基础柱体结构承载性能试验研究

Experimental study on structural performance of steel-tube-inserted foundation column in transmission line tower

针对输电线路杆塔钢管插入式基础柱体结构设计方法与参数取值不明确的问题,开展了基础柱体结构设计方法的讨论,并开展了现场真型试验研究。得到了不同钢管锚固设置与配筋情况下的柱体承载特性,提出了配骨率与位置系数的合理取值,并得出应按照构造要求进行柱体主筋与箍筋配筋的结论。

In the light of the problem of uncertain design methods and parameters of steel-tube-inserted foundation column in transmission tower,the design method of foundation column structure was discussed,and the field type test is carried out. The load characteristics of steel tubes under the different condition of anchorage and reinforcement were obtained. The reasonable values of the ratio of bone and the position coefficient were presented. It was concluded that the main reinforcement and stirrup of the column should be reinforced with the structural requirements.
