摘　　要：孔隙水压力计在实际使用过程中,通常不能按照规范那样进行现场标定,现场常采用无套管钻孔埋设孔隙水压力计,从而可能会影响孔隙水压力计精度,且在实际使用过程中量程选择也是一个难题。针对这种情形,通过分析常压标定方式误差、量程选择问题及无套管埋设孔隙水压力计,得出采用的现场常压标定及无套管埋设是可行的。In the practical application, pore water pressure gauge generally can not be calibrated on site in accordance with the rules. It is often installed by tubeless drilling-embedding, which may affect its accuracy. In addition, the selection of its measurement range is also a difficult problem. It is concluded, through the analysis of the error of the calibration at normal pressure, the measurement range selection and the tubeless embedding of the pore water pressure gauge, that the on-site the calibration at normal pressure and tubeless embedded Installastion are feasible.
