摘　　要：通过整理无锡地震监测中心站常熟地震台山洞定点形变观测资料,分析环境因素(自然环境及场地环境)、观测系统运行情况及人为干扰因素三大类因素对形变观测数据的影响,强化认识干扰形态,总结干扰特征,为提高形变观测质量提供保障,为进一步研究地震前地球物理异常提供部分依据。By sorting out the fixed point deformation observation data of the cave of Changshu Seismic Station in Wuxi Earthquake Monitoring Center,this paper analyzes the influence of three major factors,namely environmental factors(natural environment and site environment),observation system operation and human interference factors,on the deformation observation data,strengthens the understanding of interference forms,summarizes interference characteristics,and provides guarantee for improving the quality of deformation observation.It provides some basis for further study of geophysical anomalies before earthquake.
