Notes:
An earth dam was to be constructed on a site which posed non-uniform foundation conditions. The most prominent feature was a vertical contact between unweathered quartzite and decomposed diabase running parallel to the valley. The paper describes a two-dimensional finite element analysis on the foundation and embankment to determine relative settlements and the possibility of hydraulic fracturing of the clay core. The analysis was extended to evaluate the effectiveness of site improvement measures such as excavation and recompaction of the decomposed diabase and elimination of the contact problem by blasting into the unweathered quartzite. Comparing results from the various analyses, it was concluded that the latter was the only viable solution to the problem.
