| 摘 要： | 德令哈台YRY-4钻孔应变观测数据长期受环境干扰影响。本文基于多种方法，通过分析观测资料与气象因素的相关性及环境水体蓄放水的载荷影响，追溯不同水体的地球化学特征，判断钻孔应变所受干扰来源及干扰机制。研究表明，在长时间尺度上，德令哈台钻孔应变存在稳定、显著的年周期性气温、气压干扰和不稳定、细微的地下水渗漏扰动；在短时间尺度上，德令哈台钻孔应变每年4~11月前后受人工湖和水库蓄放水影响，存在载荷效应。

| 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. |
