Assessment of heterogeneity of an internal structure of an earth-fill embankment with 2-D resistivity survey
It is no doubt that any earth-fill embankments are subjected to degradation and damage after many decades of use. The present study thus attempted to use 2-D resistivity survey for mapping of an internal structure of six earth-fill embankments (dams) in Thailand that have been constructed and used for the last 47 years or more. Damage to external structure is visible and so its repair is tenable. However, an attempt to protect and restore the utility of earth-fill embankments may be too late if the damage occurring to the hidden internal structure has left undetected. Thus, for the present study, six earth-fill embankments of more than 47 years of age were selected as cases. The resistivity profiles were measured at the top and at the downstream toe of each selected embankment. The results reveal the resistivity anomaly that could be interpreted to suggest heterogeneity/homogeneity of the subsurface earth structure. However, further study is needed to be conducted for a conclusive interpretation of the heterogeneities revealed for the first time from these selected six cases of earth-fill embankments in Thailand.
