摘要
我国中西部地区输电塔在复杂地质构造、极端气候事件及多重灾害耦合作用下存在结构失稳风险，亟需针对铁塔薄弱部分提出性能可靠、安装便捷的加固方法。本研究提出基于钢绞线连接加固技术的塔体稳定性提升方法，区别于传统局部加固工艺，通过构建有限元塔线耦合模型，系统探究了风-冰荷载耦合工况、单风荷载工况及覆冰工况下塔架结构的应力分布特性与形变响应机制。研究发现：钢绞线节点强化连接技术可有效实现塔体薄弱部位的应力分布，其高强度特性使塔架在30m/s风速及20mm覆冰综合工况下的最大应力降低35.3%。通过模态参数对比分析，加钢绞线后输电塔在低阶模态时候表现为钢绞线的舞动摇摆，前2阶自振频率分别高出了9.5%、8.2%，证实该加固体系能显著改善结构刚性和动力特性。研究成果为高灾害风险区输电塔的韧性加固设计提供了量化决策依据。
Abstract
There is a risk of structural instability of transmission towers in the central and western regions of China under the coupling effect of complex geological structure
extreme climate events and multiple disasters
and it is urgent to propose a reinforcement method with reliable performance and convenient installation for the weak part of the tower. In this study
a method for improving the stability of the tower based on the steel strand connection reinforcement technology is proposed
which is different from the traditional local reinforcement process
and the stress distribution characteristics and deformation response mechanism of the tower structure under the wind-ice load coupling condition
the single wind load case and the icing condition are systematically explored by constructing the finite element tower-line coupling model. It is found that the reinforced connection technology of steel strand joints can effectively realize the stress distribution of the weak parts of the tower
and its high-strength characteristics can reduce the maximum stress of the tower by 35.3% under the comprehensive conditions of 30m/s wind speed and 20mm icing. Through the comparative analysis of modal parameters
the transmission tower exhibits the dance and swing of the steel strand in the low-order mode
and the natural frequency of the first two orders is 9.5% and 8.2% higher respectively
which proves that the reinforcement system can significantly improve the structural rigidity and dynamic characteristics. The research results provide a quantitative basis for decision-making on the resilience reinforcement design of transmission towers in high disaster risk areas.
