摘　　要：定点形变观测是地震前兆监测重要手段,为深入分析不同形变观测仪器受气象因素干扰的影响,对五指山形变台硐室倾斜和应变观测资料与温度、气压及降雨进行了相关性分析。分析结果表明三套形变仪器的观测数据与气压的相关性均较弱,倾斜仪观测数据与温度均存在较强的相关性,且垂直摆倾斜仪较水管倾斜仪相关系数更高;垂直摆倾斜仪受降雨影响最大,水管倾斜仪北南分量与伸缩仪北南分量次之,上述仪器东西分量均不受降雨影响。Fixed point deformation observation is an important means of earthquake precursor monitoring.In order to deeply to analyze the influence of meteorological factors of different deformation observation instruments,the correlation between the observation data onto chamber tilts and strain and temperature,air pressure and rainfall of deformation station in Wuzhishan was analyzed.The results show that the correlation between the observation data onto the three deformation instruments and air pressures is weak,the correlation between the observation data onto the tilt instrument and temperature is strong,and the correlation coefficient of the vertical pendulum tilt instrument is higher than that of the water pipe tilt instrument.The vertical pendulum tipper was most affected by rainfall,followed by the north-south components of the water pipe tipper and the north-south components of the telescopic instrument.The east-west components of the above instruments were not affected by rainfall.
