摘要

通过观察形变仪器受到的特殊干扰,进而注意到山洞环境对地震观测的影响。在对干扰事件的起因作深入探讨,推断此类干扰与山洞的温度、湿度相关。进一步分析显示,潮湿是山洞环境发生变化的直观反映,而山洞的温度变化则是山洞环境发生改变的主要原因,是一系列干扰的直接起因。通过对以上影响因素进行研究并试图消除环境干扰,最终可以获得正常的观测结果。由此可见,为获得准确的观测数据,避免此类干扰影响地震分析,需要创造稳定的山洞环境。
Through the observation of deformation apparatus by special interference,the change of environment in the cave was found and observed.After analysis to the special interference in detailed,this interference was supposed be associated with temperature and humidity of the cave.Further study revealed that moisture was the direct reflection of environment and change of temperature was primary cause of the obstruction.Change of temperature was the cause of other interference meanwhile.Through the study and attempted elimination on the facts mentioned above,the normal observation data was obtained.It can be concluded that for obtaining exact data and avoiding the interference on earthquakes forecast,steady surroundings should be maintained.And how to improve the heat preservation effects of the cave should cause the great attention of related aspects meanwhile.
