摘要

This study optimizes the upstream slope of the Hanota Dam on the Bina River to reduce material usage while ensuring safety compliance. Utilizing GeoStudio’s SLOPE/W and SEEP/W modules, the upstream slope is adjusted from 3.6H:1 V to an optimized 2.5H:1 V above the berm level. Detailed simulations under critical conditions reveal a 12.98% reduction in dam volume and a 55,110 m2 reduction in ground area. The optimal configuration maintains the required Factor of Safety for all conditions specified by IS:7894–1975. The study demonstrates the effectiveness of computational tools in optimizing earthen dam designs, achieving material savings while meeting safety requirements.
