摘　　要：结合福州市地铁某车站工程实例,通过对AM工法灌注桩竖向抗拔静载试验的抗拔方案设计和试验成果整理,分析了AM工法桩的桩身抗拔承载力和试验成果关系曲线的一些特性,结果表明:AM工法扩底灌注桩作为软土地区大吨位抗拔桩是适用可行的,相对于等直径桩可提高较大的抗拔力。According to a project of Fuzhou Metro station,through designing the scheme of static load test by cast-in-place pile of the measure of AM,and arranging the test results,analyzing some characteristcs of the pullout capacity of the pile by the measure of AM and the curve of the test results. It can be concluded that the AM method of bottom-enlarged cast-in-place pile as large-tonnage uplift pile is suitable for the soft soil foundation. Compared with the equal diameter pile,it can also increase the pullout resistance.
