Effect of Material Property in Foundation during Earthquake on the Embankment

Abstract EN

The dynamic analysis process started after any loss of embankment with associated huge damages like cracks during the earthquake.

Literature review indicated that the maximum displacement during the earthquake is conducted to the crest and interface between the embankment with water reservoir, and foundations were cased.

This paper evaluated the effect of material properties of the foundation for the two conditions so the result is related at the end of construction with supplying water.

Numerical analyses of models were performed by finite element with plane strain method and ANSYS13 software.

Earthquake recording as Nagan with 5.02 seconds and peak ground acceleration equal to PGA=0.65 is used.

Results indicated that with a comparison of horizontal and vertical displacement, shear strain and shear stress so nonisotropic behavior of embankment especially in the up to part of the structure was obvious.

It is required to consider an improvement of dynamic settlement with reinforcement structure in the future.
