Abstract
In recent years,clean energy represented by wind power generation has developed rapidly,especially in inland wind farms,which have increasingly intersected with water conservancy,hydropower,mining,highway transportation and other engineering projects.In the construction process of these projects,it is inevitable to involve the situation of open-pit blasting excavation near wind farm fans.This article takes wind farm fans as the research object,combines relevant regulations and specifications with finite element calculations,and proposes blasting vibration control standards for wind farm fans near the open-pit blasting area.Taking specific projects as examples,combined with three-dimensional finite element models,the dynamic response of wind farm fans is analyzed,and the control standard for blasting single-stage explosive dosage is obtained.The results can be used as a reference for similar projects to guide design and on-site construction,and avoid the impact of blasting vibration on wind farms.Normal operation of wind turbines in the power plant.关键词
