以输电线塔-高边坡为主要研究对象,考虑输电线塔振动作用,研究边坡在风荷载引起的输电线塔振动作用下的动力影响。利用MATLAB软件对作用在输电塔线体系上的顺风向风荷载进行数值模拟,得到脉动风时程曲线,加载到建立的输电线塔-高边坡体系上,进行体系的有限元分析。以广贺高速公路某路堑高边坡为实例,通过有限元软件ANSYS模拟计算,分析了风载对边坡以及开挖过程中的边坡的影响,以此说明在边坡的稳定分析设计中,考虑风荷载的重要性。
Taking the transmission line tower - high slope as the main research object, considering the vibration of transmission line tower, the dynamic influence of slope on the vibration of transmission line tower caused by wind load is studied. The MATLAB software was used to simulate the downwind wind load acting on the transmission tower system, and the time history curve of the fluctuating wind was obtained and loaded into the established transmission tower-high slope system, and the finite element analysis of the system was carried out. Taking the high slope of a highway in Guanghe Expressway as an example, the influence of wind load on the slope and the slope during excavation is analyzed by the finite element software ANSYS. The results show that in the slope stability analysis and design , Consider the importance of wind load.
