中文摘要	Study on hysteresis phenomenon of piezometer tubes through comparing reading of pore water pressure sensors and piezometer tubes has been carried out. Some conclusions have been gained. Hysteresis phenomenon is more obvious with the distance of piezometer tubes to soil bottom increasing. Hysteresis phenomenon of piezometer tubes at soil middle is always obvious until the periodicity reaches 20.8 min. But head loss and hysteresis phenomenon both are small near soil bottom whatever the periodicity is. Hysteresis phenomenon can be ignored when the periodicity reaches 46.5 min. It shows that dry density has some influence on hysteresis phenomenon. Hysteresis phenomenon because of effect of different dry densities becomes small with increasing of the periodicity.
