摘要
介绍了三种桥台结构改进及加固方法,并利用大型有限元软件Ansys,对倒角法和预应力钢筋混凝土圈梁法进行了非线性有限元仿真模拟,分析得出此两种方法能有效的达到加固重力式U型桥台的目的。
The paper introduces improvement and reinforcements of 3 categories of abutment structures, and makes non - linear finite element emulative simulation of chambering method and ring beam method for prestressed reinforced concrete with large - scale finite element software Analysys. Analysis gained that these two kinds of methods attain all effectively goal to reinforce gravity U -type abutment.
