Abstract:The observation data of Delhi YRY-4 have been affected by environmental interference for a long time. Based on various methods, this study judges and analyzes the interference source and mechanism of borehole strain by analyzing the relativity between observation data and meteorological factors, the load influence of environmental water storage and release, and the geochemical characteristics of different water bodies. The results show that there are stable and significant annual periodic air temperature and pressure disturbances, unstable and subtle groundwater leakage disturbances on a long time scale. In a short time scale, there exists load interference of water storage and release in artificial lakes and reservoirs, which last from April to November every year.
