风积沙地区加筋地基铁塔基础技术经济研究

Technical and economic research on reinforced tower foundation in aeolian sand area

中国是荒漠面积最大的发展中国家之一,此类区域包含了大量的太阳能、风能等洁净资源,随着光伏风电装机迅速扩大,这些地方迫切需要大量修建输电网络以优化供电结构,实现洁净能源外送需要。根据风积沙区域地质条件特征,对三种常规基础设计方案进行了技术经济对比分析,提出抗拔加筋复合地基基础方案是最经济的,同时其计算结果可当作方案比选、投资估算依据,也可当作工程造价及相关机构的现阶段参照指标。

China is one of the developing countries with the largest desert area,such areas contain a large number of solar,wind and other clean resources.With the rapid growth of photovoltaic and wind power installed capacity,there is an urgent need to build a large number of transmission networks in these places to optimize the power supply structure and achieve clean energy delivery needs.Based on the geological conditions of the aeolian sand area,the technical and economic comparison analysis of three conventional foundation design schemes is made,and it is proposed that the scheme of anti-pulling and reinforced composite foundation is the most economical.At the same time,its calculation results can be used as the basis for scheme comparison and investment estimation,as well as the current reference index for engineering costs and related institutions.
