摘　　要：文章对南京河西某大吨位锚桩法静载试验过程进行讨论、实施与总结,分析与研究试验方法,采用“六锚一”的方法并结合双套管段桩身变形量的测试与理论值的比对,发现桩身压缩量在总沉降量中占很大比重,在实际应用中予以考虑,可准确地获得深部有效桩的承载力。Through to a big tonnage static load test of anchor pile method in the nanjing hexi in the process of discussion,implementation and summary,analysis and research on test method,adopt the method of six anchor combined with double pipe section of the pile body deformation test and the theoretical value,found that the quantity of pile body compression accounts for a large proportion in the total settlement,shall be deducted in the practical application,The bearing capacity of deep effective pile can be obtained accurately.
