A hill with a lattice transmission tower presents complex wind field characteristics. The commonly used computational fluid dynamics (CFD) simulations are difficult to analyze the wind resistance and dynamic responses of the transmission tower due to structural complexity. In this study, wind tunnel tests and numerical simulations are conducted to analyze the wind field of the hill and the dynamic responses of the transmission tower built on it. The hill models with different slopes are investigated by wind tunnel tests to measure the wind field characteristics, such as mean speed and turbulence intensity. The study shows that the existence of a transmission tower reduces the wind speed on the leeward slope significantly but has little effect on the windward slope. To study the dynamic behavior of the transmission tower, a hybrid analysis procedure is used by introducing the measured experimental wind information to the finite element tower model established using ANSYS. The effects of hill slope on the maximum displacement response of the tower are studied. The results show that the maximum value of the response is the largest when the hill slope is 25° compared to those when hill slope is 15° and 35°. The results extend the knowledge concerning wind tunnel tests on hills of different terrain and provide a comprehensive understanding of the interactive effects between the hill and existing transmission tower regarding to the wind field characteristics and structural dynamic responses.

具有格子输电塔的山丘呈现出复杂的风场特征。由于结构复杂，常用的计算流体动力学（CFD）模拟难以分析输电塔的风阻和动力响应。在这项研究中，通过风洞试验和数值模拟来分析山丘的风场和建立在山上的输电塔的动力响应。通过风洞试验研究不同坡度的山地模型，以测量平均速度和湍流强度等风场特性。研究表明，输电塔的存在显着降低了背风坡上的风速，但对迎风坡影响不大。为了研究输电塔的动态行为，通过将测量的实验风信息引入使用 ANSYS 建立的有限元塔模型，使用混合分析程序。研究了坡度对塔最大位移响应的影响。结果表明，与坡度为15°和35°时相比，坡度为25°时响应的最大值最大。结果扩展了有关不同地形山丘风洞试验的知识，并全面了解山丘与现有输电塔之间在风场特性和结构动力响应方面的相互作用。研究了坡度对塔最大位移响应的影响。结果表明，与坡度为15°和35°时相比，坡度为25°时响应的最大值最大。结果扩展了有关不同地形山丘风洞试验的知识，并全面了解山丘与现有输电塔之间在风场特性和结构动力响应方面的相互作用。研究了坡度对塔最大位移响应的影响。结果表明，与坡度为15°和35°时相比，坡度为25°时响应的最大值最大。结果扩展了有关不同地形山丘风洞试验的知识，并全面了解山丘与现有输电塔之间在风场特性和结构动力响应方面的相互作用。
