软土地区高路堤地震破坏特征有限元分析
|
摘要
在重大灾害的抢险救灾中,公路运输是缩短救援人员和物资运抵灾区的重要保障。与桥梁工程不同,公路设计中一般不会进行地震条件的路堤动力分析,但软土地区的高路堤公路在地震作用下破坏特征将会影响到破坏公路的疏通工作量。基于总应力法和有限元动力分析方法,应用ANSYS软件研究了软土地区高路堤公路地震破坏特征。
Rushing to deal with an emergency and natural disaster,high way transportation is important to be reducing the transportation time for rescuer and material into disaster area.Difference from the designing bridge,the dynamic analysis of roadbed is not usually done at the condition of earthquake,but the earthquake failure character of high roadbed will influence the amount work of opening up the broken highway.On the bases of the total stress method and the dynamic analysis of FEM,the earthquake failure character of soft ground's high roadbed is analyzed by the ANSYS softer.
