Abstract:
The underground fluid observation data of well Dian 02 in Yuanmou hydration station from 2008 to 2024 are selected, and four types of interference are sorted out by comparing with normal observation data, which are observation technical system failure, site environment interference, human factor interference and other accidental interference. The prediction efficiency of the underground fluid observation data of Yuanmou Hydration Station is analyzed. The prediction efficiency R value of all the underground fluid observation data of Yuanmou Hydration Station is calculated by threshold method, rate difference method, trend turning method and annual change detection method. The results show that the
R values calculated by the four methods of water temperature, water level and gas radon are all greater than 0, indicating that it has predictive significance. The prediction efficiency of water temperature calculated by the rate difference method is
R >
R0, indicating that it has significant predictive significance. The
R values calculated by the four methods of gas mercury are all less than 0, indicating that gas mercury has no effective predictive significance.
