水厂抽水对乌什地震台体应变观测数据的干扰分析

The Interference of Water Pumping on Body Strain Observation Data in Wushi Seismic Station

根据体应变的观测原理,从理论和实际观测中分析了水厂抽水对体应变观测分钟值曲线的影响及两者间的相关性。分析表明,应变观测值波动时间与抽水时间基本吻合,因此认为水厂抽水对体应变观测会造成一定程度的干扰。

In accordance with the principle of strain, the disturbing influence of water pumping on the curve of minute value in the body strain is analyzed from the theory and practice, and the relations between the two are analyzed too. The analysis shows that the strain observation fluctuations in the value of time and changes in direct proportion pumping relations. It says they are in consistency. So the pumping water plant may, to some extent, distort the body strain observation data.
