Abstrait:

The 289m high arch dam at Baihetan has good indicators before water storage, but after water storage, seepage gradually occurs in the dam body and foundation parts, which has some adverse effects on the safety of the dam. In this paper, five monitoring instruments were used to analyze the overall dam properties during the water storage process, including the pre-buried foundation corridor pressure tube, the dam base seepage pressure gauge, the seepage pressure tube around the dam, the dam water measuring weir and the dam base drainage hole. The results show that: the seepage pressure level before the curtain of the dam base is seriously affected by the upstream water level, Post-curtain and post-drainage lift pressure is less affected by upstream water level; the flow rate of the dam measuring weir and the dam base drainage hole is more affected by the upstream water level, and the trend of flow rate changes is more consistent with the trend of the upstream water level; the rest of the parts are less affected by the upstream water level.
