| 1. | The preferences are analyzed , pipe ’ s parameters such as depth , thickness , pipe diameter , and mechanical property of material ; soil parameters such as soil types , internal friction angle , pipe - soil interaction ; fault ’ s parameters such as fault types , fault throw , fault drop , fault - pipe angle , mechanical property of material ; load types such as gravity force , linear displacement load , seismic load and seismic wave . some conclusions are drawn from the calculating results : when buried pipes cross fault , pipe ’ s embedded depth should be shallow , and big pipe diameter and thick wall should be selected . avoid the site where fault moves severe , and select suitable pipe - fault angle
在有限元三维模型建立中考虑的因素有:管道自身参数如管道埋置深度、管壁厚度、管径、管道材料等;岩土材料参数如土体类型、岩土的内摩擦角、管土相互作用等;断层考虑有断层类型,断层断距,断层错动距离,断层与管道的交角,断层材料的考虑等;荷载分别考虑静荷载,动荷载,其中动荷载包括线性位移加载、地震力加载和地震波加载等。 |
