摘要
应用相关和回归分析方法,研究乌什台体应变与温度、气压、水位之间的关系。结果表明,气温是影响乌什体应变年周期变化的主要因素,体应变相位滞后气温约322d;气压对乌什体应变年频段信息的影响较小,但对体应变日变化影响较大。探讨了气温与气压影响体应变的可能机制。
Using correlation and regression analysis methods,this paper studies the relation between Wushi strain and air temperature,air pressure and water level.The results show that the air temperature is the main factor affecting the body strain year period in Wushi-the borehole body strain＇s phase hysteresis temperatures is about 322 days.The influence of air pressure strain year frequency is weaker on Wushi borehole body strain,but affectsthe main factors of diurnal variation.Further we explore the possible mechanism of the influence of air temperature and air pressure on borehole body strain.
