摘　　要：利用大型有限元软件Ansys对各种尺寸的重力式U型桥台进行非线性仿真模拟,分析得出台后巨大的土压力是造成台身开裂的主要原因。另外,通过模拟也可以了解到何种尺寸的重力式U型桥台相对安全。The paper makes nonlinearity emulating simulation of gravity U - type abutment with different size using the large -scale of finite element software, anylyzes and finds the heavy soil pressure behind abutment is a major reason for abutment body crack. In addition through simulation it can be known that a kind of dimentional gravity U -type abutment is relativly safe.
