Analysis on Dynamic Characteristics of Lime-soil Pile Composite Foundation of Low Embankment along High-speed Railway
摘要
Abstract
Using finite element software MIDAS/GTS, the three-dimensional finite element models for railway subgrade on both lime-soil pile composite foundation and untreated loess foundation are established respectively. Through simulating train load through the use of track irregularities, dynamic stress distribution in foundation soil thatg in different embankment heights and under the action of train load at different velocities is analyzed and calculated, and then the change law of pile-soil stress and instantaneous deformation law of foundation are obtained.关键词
