DEM을 이용한 자갈도상의 응력분포에 관한 연구
Study on the stresses distribution of ballast bed using DEM (Discrete Element Method) Analysis
- 발행 : 2005.11.01
초록
Sleeper, the ballast, and ballast mat in the high-speed railroad line are modelled using a two-dimensional discrete element method to generate circle and line elements. Stress transfer mechanism from the sleeper to the subgrade via the ballast is analyzed. The behavior of ballast bed of the high-speed railroad line is also accessed with the model.
