摘　　要：农村生活及春季农田灌溉等所需水源大部分通过抽取地下水解决,而水井抽水直接影响体应变观测。为此,就3种情况下体应变资料受水井抽水的影响进行分析,可为台站人员排除体应变的干扰因素、获得准确的数据资料提供帮助。Volumetric strain observation data is influenced by pumping more rural living and spring farmland irrigation water.In this paper,three cases of influence by water pumping are analyzed.It is hoped that the study can provide some help in eliminating the interference factors of volumetric strain and to obtain accurate data.
