摘　　要：四川数字地震观测网络项目前兆分项目建设已通过中国地震局监测司的验收,四川前兆钻孔应变仪台站观测系统已运行一年多,从观测工作的各个环节都有值得总结和分析的必要,从而更好地服务于地震预报和科学研究。The tasks of checking and accepting of the precursory sub-project, project of digital seismic observation network in Sichuan Province, had been finished by the Monitoring and Prediction Department of China Earthquake Administration. The observation system of borehole strain meters had operated for more than one year. Through operation of borehole strain meters, we think that the goodness of the meter operation relies mainly on following the factors, for examples, the continuity and voltage change of power supply, meter troubles, environment stability of seismic station and skillful level of operator and so on. There are some of changes before and after a medium-strong earthquake.
