山区风电场新型筒承式风机基础设计及生态环境效益分析

Design for New-Tube-supported Wind Turbine Foundation of Wind Farms in Mountainous Areas and Analysis on Its Ecological and Environment Benefits

摘要:

文中以重庆某山区风电场工程为依托，创新性提出适用于陡峻山区风电场的新型筒承式风机基础。通过对比分析，新型筒承式风机基础较常规扩展基础在占地和植被的影响、土石方开挖量、弃土量的影响和对水土流失量的影响等生态环境效益方面具有显著的优势。筒承式风机基础实现了对生态环境的最少破坏，能够有效减少永久占地面积、土石方开挖量和弃土量、水土流失量，为建设“生态风电”提供良好的示范。

Abstract:

Based on a wind farm project in a mountainous area in Chongqing, a new type of tube-supported wind turbine foundation suitable for wind farms in steep mountainous areas is creatively proposed. Through calculation and comparative analysis, the new type of tube-supported wind turbine foundation has more significant advantages in ecological and environmental benefits than the conventional expanded foundations, such as the impact on land occupation and vegetation, soil and rock excavation volume, spoil volume and the amount of soil erosion, which can realize the minimal ecological destruction, effectively reduce the permanent area covered, the oil and rock excavation volume, spoil volume and the amount of soil erosion, and provide a good demonstration for the construction of "ecological wind power".
