为了研究大直径钻孔灌注桩承载特性，用 ADINA 仿真手段结合现场荷载试验进行对比，研究表明：在一定范围内，随着桩径的增加，承载能力增强，桩顶位移较小，而桩径过大则会影响大直径钻孔灌注桩竖向承载力；在实际工程实践中，极大提高桩身混凝土等级，对桩基承载力的提高不明显。
為瞭研究大直徑鑽孔灌註樁承載特性，用 ADINA 倣真手段結閤現場荷載試驗進行對比，研究錶明：在一定範圍內，隨著樁徑的增加，承載能力增彊，樁頂位移較小，而樁徑過大則會影響大直徑鑽孔灌註樁豎嚮承載力；在實際工程實踐中，極大提高樁身混凝土等級，對樁基承載力的提高不明顯。

In order to study the large-diameter bored pile bearing properties,combined with on-site load test using ADINA simulation methods were compared. Studies show that:within a certain range,with the increase the diameter of the pile bearing capacity also increased,smaller dis-placement pile,and the pile diameter is too large vertical bearing capacity of large diameter bored impact,in actual engineering practice,greatly increasing pile of concrete grade,to improve the bearing capacity of the pile is not very obvious.
