Abstract

This paper is concerned with the interpretation of the observed and predicted performances of a full-scale trial embankment, which was constructed for the design purposes regarding a new bypass road to be constructed over soft clay adjacent to existing structures. The prediction based on the finite element analyses and the determination of soil parameters are briefly outlined. The results of comparison show adequate agreement between the predicted and observed field time-dependent deformation behavior throughout the entire loading history. However, if the predictions from the present FE-analyses are made by using the soil parameters measured in the laboratory, a correction factor of 6 on the value of coefficient of consolidation is required to obtain reasonable agreement with the field behavior. Finally, the practical suggestions are made for assessing the effect on the nearby existing structures of soil movements towards the outside of embankment.

Performance of Trial Embankment on Soft Clay

This paper is concerned with the interpretation of the observed and predicted performances of a full-scale trial embankment, which was constructed for the design purposes regarding a new bypass road to be constructed over soft clay adjacent to existing structures. The prediction based on the finite element analyses and the determination of soil parameters are briefly outlined. The results of comparison show adequate agreement between the predicted and observed field time-dependent deformation behavior throughout the entire loading history. However, if the predictions from the present FE-analyses are made by using the soil parameters measured in the laboratory, a correction factor of 6 on the value of coefficient of consolidation is required to obtain reasonable agreement with the field behavior. Finally, the practical suggestions are made for assessing the effect on the nearby existing structures of soil movements towards the outside of embankment.
