摘要
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。
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- suits 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.
