摘　　要：根据呼和浩特地区的地质及风资源状况,研究无地基时直接在地面安装光伏支架的可行性。通过将支架底部的横跨端用地锚与地面钉接,理论计算地锚被拔出时所受的力,与实测对比得出地锚拔出所受力与风速关系的规律,依据该规律确定无地基光伏支架在自然环境下运行是否稳定。如果方案可行,则既可缩短光伏电站的建设时间,又可降低光伏发电的投资成本,对今后国内光伏市场的大规模启动具有重要意义。According geological characteristic and wind resource reserve in Hohhot, the feasibility of installing PV bracket without foundations was anchor by directly connecting bottom parts of PV bracket to the ground with anchor. Based on this experiment, the tilting moment under wind, which the anchors were drawn from the ground can be calculated both theoretically and practically. The relationship will confirm whether brackets without ground founda- tions can work stably in natural circumstances. If it works positively, it will shorten constructing time and cut investment, and play important role in the large-scale construction for domestic solar market.
