Abstract: Crack detection and numerical simulation analysis were conducted for Lijiaxia dam, which explained the impact of cracks on dam structure safety, and provided technical support for economic operation of reservoir during non-flood period. The analysis showed that due to reservoir water level rise, the crack would extend to a certain degree and be in a stable state, which would not exert significant impact on dam safety.

Key words: dam, crack, analysis
