摘　　要：体应变观测是地壳应力应变状态及其变化规律的重要研究手段。该文整理、分析黄山台体应变历年观测资料发现,体应变日变明显,固体潮清晰,但受自然环境干扰较大,与降雨、水位呈现正相关性;与气压相关系数达0.9以上,同时也受到观测系统稳定性的影响。通过总结干扰因素和对应变化特征,希望给其他体应变观测台站提供参考资料。Volume strain observation is an important means to study the state and variation law of crustal stress and strain.This paper collates and analyzes the body strain observation data of Huangshan Station over the years.It is found that the daily variation of body strain is obvious and the solid tide is clear,but it is greatly disturbed by the natural environment,which is positively correlated with rainfall and water level;the correlation coefficient with air pressure is more than 0.9.It is also affected by the stability of the observation system.By summarizing the interference factors and corresponding variation characteristics,it is hoped to provide reference data for other volumetric strain observation stations.
