Integrated Stability and Structural Performance Evaluation of An RCC Gravity Dam Under Multi-Load Conditions
Abstract
Gravity dams are among the most reliable hydraulic structures due to their ability to resist external forces primarily through self-weight. This project presents a comprehensive structural and stability analysis of a Reinforced Cement Concrete (RCC) gravity dam considering critical loading conditions such as water pressure, uplift pressure, silt pressure, and seismic forces. Detailed site investigation data, hydrological parameters, and foundation characteristics were incorporated to ensure realistic design assumptions. Stability checks against sliding, overturning, and foundation overstress were performed using analytical methods in accordance with standard dam design guidelines. Additionally, structural modeling and verification were carried out using STAAD. Pro to validate manual calculations. The results demonstrate that the designed gravity dam satisfies all safety requirements with adequate factors of safety, confirming its structural integrity and suitability for long-term operation. The study highlights the importance of uplift pressure consideration and combined load effects in ensuring the overall safety and performance of gravity dams
