Abstract: Using finite element numerical model, combined with the geological conditions, material char⁃ acteristics and seepage field, a deep analysis of the seepage stability status of Luotian reservoir dam is conducted, and the safety performance of the dam is evaluated comprehensively. The results show that the seepage control of Luotian reservoir dam is good under various operation conditions, the saturation line rises as the reservoir water level rises, the seepage flow has little influence on reservoir water stor⁃ age, and the safety factor of anti-sliding stability can meet the requirements of regulations. The research results can provide theoretical support and technical assistance for the safe operation and management of Luotian reservoir dam, and can also provide useful references for the safety evaluation of seepage sta⁃ bility of similar projects.
