Effectiveness of Sand for the Construction of Zoned Embankment

Godfrey Jaja, Moseph Jonathan

Abstract


This study aimed at investigating the suitability of Fine and Coarse sand as fill materials for zoned embankment. The results of both the laboratory tests done on sand and gravel and the limit state equilibrium analysis using Morgenstern Price method of analysis showed safety factors and at what extent of slope the materials used would be safe. Coarse sand filling materials are suitable for constructing zoned embankment but is limited to certain slope angles. Considering seepage at a steady water head of 1m and an embankment of 1.5m high, the least factor of safety was 1.736. Further sloping beyond this is considered unsafe.
