Abstract

Summary

Geoelectrical measurements were used in association with soil engineering tests in environmental engineering investigations at Tenth of Ramadan city, east Nile Delta, Egypt. The genetic algorithm (GA) approach with structure-based (SB) model is applied towards an optimal interpretation of DC resistivity measurements. The inverted models together with borehole data and soil classification exhibit two soil types, gravelly sand and clayey sand with free lime. The survey demonstrates that the combined use of the GA with SB model provides valuable information to constraint the number of interfaces. The reliable resistivity inversion results are considered as a key role in studying the geotechnical parameters such as Atterberg limits unconfined compressive strength and swelling tests. The clay sediments are described by medium plasticity and sensitivity for swelling. Further, the free lime with water makes gill action with decreasing the compressive strength. Therefore, such soil, in turn, may cause soil water appearance on the ground surface and geotechnical problems during or after the process of any construction. In this respect, the integration of the geoelectrical survey with soil engineering properties is efficient and less time consuming for characterizing the engineering-geologic zone.
