哑铃型承台群桩基础在船撞作用下受力分析

摘要

By taking the dumbbell shaped cap supporting of cable-stayed bridge as the research object,this text analyzed the rule of horizontal bearing for the pile group foundation under ship impact load case,using finite element analysis software Midas-civil&Ansys. The calculation re-sults show that there has obvious difference between the numerical calculation and the traditional“m”method,and the numerical calculation are more tally with the actual situation compared with the“m”method.%以某斜拉桥哑铃型群桩基础为研究对象，运用Midas-civil及Ansys有限元计算软件，分析了哑铃型群桩基础在船撞荷载工况作用下的水平向受力规律，计算结果表明数值模拟分析结果与传统“m”法计算存在较大差别，有限元分析结果更符合实际情况。
