中文摘要	在宁夏毛乌素加筋风积沙地基中开展偏心装配式基础在单上拔、上拔与水平力组合工况下的现场对比试验,通过监测其顶部荷载位移曲线、地表竖向位移及基础底板土压力数据,分析偏心装配式基础的抗拔承载机理。试验表明:采用增强地基稳定的加筋和设置基础偏心的结构措施,可显著改善装配式基础的受力性能,在提高其抗水平承载性能的同时不降低其抗拔性能,为沙漠地区输电线路工程中应用装配式基础提供了试验数据。
英文摘要	On geogrid reinforced aeolian sand ground in Ningxia, a full-scale in-site comparison experiments of the uplift bearing capacity for eccentric assembly foundation were tested under uplift loading and uplift combined with horizontal loadings. Both the site conditions and the load tests were recorded comprehensively, allowing for a thorough evaluation of the loading-displacement behavior. Based on the displacement of top plane of foundaiton and the soil reaction forces, the mechanism of the the eccentric assembly foundation on reinforced aeolian sand ground was obtained. Through taking geogrid reinforcement and eccentric structure measures, the bearing performance of assembly foundation was significantly improved, which could improve its anti-horizontal bearing capacity and did not reduce the uplift performance. The test result provided useful evidence for its practice in transmission line projects in aeolian sand.
