孔隙水压力观测是水利工程安全监测的重要项目之一。孔隙水压传感器使用前必须进行现场标定。本文结合青海温泉水库应用的电感调频式传感器，介绍了简单实用的现场标定及压力误差修正方法，既适用于即将埋设的仪器，又能对未标定已投入使用仪器的误差予以修正，对该类仪器的正确使用有较高的实用价值。
Pore water pressure observation is one of the important items of water conservancy project safety monitoring. Pore water pressure sensors must be field calibrated before use. In this paper, a simple and practical method of on-site calibration and pressure error correction is introduced based on the inductive frequency modulation sensor used in Qingquan Hot Spring Reservoir. It is not only suitable for the instrument to be embedded, but also can correct the error of the instrument which has not been calibrated. The correct use of the instrument has a high practical value.
