摘要
利用有限元软件ANSYS建立桩网结构路基模型,同时结合郑西客运专线实际工况,加载1976年宁河天津地震波,对桩网结构路基的地震动力响应进行数值模拟,并对动力响应的结果进行分析.
In combination with the actual condition of the Zhengxi passenger railway line, the pile-net struc- ture roadbed solid model is established by using finite element software ANSYS. By inputting the earthquake wave in Tienjin Ninghe （1976）, the dynamic response of pile-net structure roadbed is simulated in terms of dynamic displacement and the stress under earthquake load.
