摘　　要：本文从设计角度出发,介绍凤城—梅里长江大跨越工程基础试桩及设计方案,并针对杆塔与基础连接型式、基础变形控制、渗流等内容进行了分析。结果表明:软土地质条件下,超长桩应按照摩擦桩进行设计;跨越塔与基础采用内外双圈地脚螺栓型式;连梁可显著提高基础抗水平变形能力。From the point of view of design,this paper introduces the foundation design and pile test scheme of Fengcheng Meili Yangtze River crossing project.The connection between tower and foundation,foundation deformation control and seepage are analyzed.The results show that the super long pile should be designed as friction pile in soft soil;Internal and external double circle anchor bolts are used for connection between crossing tower and foundation;Coupling beam can significantly improve the horizontal deformation resistance of foundation.
