摘要

摘要: 为了实时掌握逾龄输电铁塔结构的健康状态，针对山东临沂4基正在运行的输电铁塔建立了基于无线传感网的结构健康状态监测系统，通过有限元分析确定了铁塔结构的控制部位和损伤敏感部位，实现结构工作应力、变形、振动及基础位移、沉降等结构健康状态信息的在线实时监测。结果表明，监测系统运行状态良好，应变、振动、沉降等监测数据波动稳定，铁塔结构健康状态无异常，有效保障了输电铁塔的安全稳定运行。

Abstract: To grasp the health status of overage transmission tower structures in real time, this paper built a wireless sensor network-based structural health status monitoring system for the four transmission towers currently in operation in Linyi, Shandong Province. The control parts and damage-sensitive parts of the tower structures were determined by finite-element analysis. The working stress, deformation, and vibration of the structures, foundation displacement and settlement, and other information about the health status of the structures were thereby monitored online in real time. The results show that the proposed monitoring system operates well and the monitored data on the strain, vibration, and settlement fluctuate steadily. Moreover, the health status of the tower structures exhibits no abnormality. In this way, the proposed system effectively guarantees the safe and stable operation of the transmission towers.
