Abstrait:

This paper has studied on the seepage and deformation analysis of a tailing dam in the upper reservoir of the Tiantai Pumped Storage Station. The analysis of seepage and deformation is crucial for evaluating the stability and safety of the dam and its impact on the surrounding environment. The study uses numerical simulation software (Phase2 and FLAC3D) to analyse the behaviour of the dam under different drainage conditions and construction phase. The results indicate that two drainage schemes in different filling stages are effective. In the same cross-section of the rock and soil basement, the flow rate of the no dumped and dumped slope is 0.0315 L/s and 0.0319 L/s respectively. The filling of the tailing dam has no predominant impact on the internal deformation magnitude of the auxiliary dam, but it changes the direction of the slope deformation from being squeezed out towards the lower slope to being towards the near-vertical direction, achieving a stable slope. Therefore, it is necessary to ensure the drainage function of the anti-filter layer and the deep interceptive drainage ditch and strengthen the monitoring of slope deformation during the construction phase.
