    摘要:

    架空配电线路电杆使用数量大、分布范围广,在极端天气条件下易发生倾覆,对局部区域甚至整条配电线路的供电产生威胁。如何借助科学有效的方法对电杆的抗倾覆能力进行仿真建模与分析,现已成为配电网建设与改造过程中的关键技术问题。针对该问题,以10 kV钢筋混凝土电杆为例,首先,结合气象条件对其荷载及内力情况进行计算;其次,基于FLAC3D软件,提出一种架空配电线路电杆抗倾覆能力仿真建模与分析方法;最后,结合河南某地区土体参数开展算例分析,详细分析极端天气条件下地基基础的变形破坏过程并绘制荷载—位移曲线,可为架空配电线路电杆的安装和加固提供技术支撑。

    Abstract:

    Overhead distribution poles are widely distributed with large quantity. However, the poles are prone to overturning under extreme weather conditions, which threaten the power supply of local areas or even the entire distribution line. How to apply scientific and effective methods to simulate and analyze the anti?overturning ability of poles has now become a key technical issue in the construction and transformation of distribution networks. To address the problem, this paper takes 10 kV reinforced concrete poles as an example, the load and internal force considering meteorological conditions are calculated first. Then, based on the FLAC3D software, a simulation modeling and analysis method for the anti?overturning ability of distribution poles is proposed. Finally, a calculation analysis of example is carried out in combination with soil parameters in a certain area of Henan. The deformation damage process of the foundation under extreme weather conditions is analyzed in detail and the load?displacement curve is drawn. The contribution of this research can provide technical support for the installation and reinforcement of distribution poles.
