| 摘 要： | 地下水位异常在地震前兆信息中占有重要地位,但观测资料所受干扰较多,异常成因较为复杂,探寻水位异常来源对准确判断震情有重要作用.该文在对安徽霍山皖33井水位1998年以来的资料进行系统清理总结以及环境干扰进行较为详细的调查分析的基础上,通过观测系统准确性的对比试验,得出以下结论:水位基本不受环境因素干扰,但观测系统是影响水位突变的一个不可忽视的因素.在排除干扰异常,提高水位观测质量,以获取更为可靠的地震前兆信息方面进行了有益的尝试.

| Abstract: | Water level observation data can be influenced by various factors or be caused by complicated reasons,therefore,research on the causesof abnormity is of significant importance in terms of the earthquake prediction accuracy.In this paper,we give a systematic analysis of the water level changes of Huoshan 33 well in Anhui province since 1998 and a detailed investigation of the environmental influences on the water level changes.Further comparative experiments with the observation system show that the environm... |
