[P02-09] Stress analysis on construction and in-service to embankment considering construction conditions

Keywords:Embankment, Unsaturated soil, Construction condition

In recent years, many examples of soil structure collapse due to heavy rainfall have occurred. Because of this, it is urgent to establish a method to evaluate and examine long-term embankment structure quality. Conventional design method insufficiently evaluates embankments. Although this method is shifting to a performance-based design, an effective design method has not yet been established.
Therefore, this research performs stress analysis of embankment, accounting for differences in construction conditions. Based on the dynamics of unsaturated soil, the dynamic change in embankment performance was analytically expressed, and the optimal structural conditions of embankment, grouped by rainfall history, was examined.
