潜水含水层水位观测孔水位伪变化的观测与分析

结合CIRP试验场包气带的介质结构及渗透性特征，在S9孔进行了短期的孔中水位、孔口气压和温度测量，测量结果表明，观测孔水位波动与大气压变化有关，水位波动具有伪变化。水位伪变化对于试验场潜水位的监测有一定影响，因此，应对带有伪变化的水位观测结果进行必要的修正，以反映潜水位的真实动态。

Analysis and Observation of Water Level Pseudo-change of The Observation Hole for The Phreatic Water

A short-term measurement of water level,gas pressure and temperature in the S9 hole are maken combining with medium structure and perviousness character of the CIRP testing field.It shows that the water level change is related to air pressure,so water level chang has pseudo-change character.The pseudo-chage has impact on water level montoring of the phreatic water,so it is necessary to correct.Then the real dynamic chang can be found.
