本文针对国内首个单墩P&H无张力新型风力发电机基础应用于湿陷性黄土地质条件的风电场——国电陕西草山梁风电场进行了工程实例综述和工程造价对比分析。通过对比分析显示,单墩P&H无张力新型风力发电机基础非常适用于中国西北部湿陷性黄土地质条件,在保证风机基础稳定性的前提条件下,极大地降低了工程造价,降低征地面积,并缩短了工期,在西北部湿陷性黄土地质条件下具有很好的推广价值。
In this paper, the first single-pier P & H tension-free new wind turbine foundation applied to collapsible loess geological conditions of the wind farm - State Power Shaanxi Caoshangliang wind farm project examples and project cost comparison. The comparative analysis shows that the foundation of a single pier P & H tension-free wind turbine is very suitable for the geological conditions of collapsible loess in northwestern China. Under the premise of ensuring the stability of fan base, the project cost is greatly reduced, the land acquisition area is reduced, And shorten the construction period, which has a good promotion value under the collapsible loess geological conditions in the northwest.
