Matric suction, ground movement, water content, ground temperature, and daily weather data including: precipitation, potential evaporation, air temperature, relative humidity, sunshine hours, and wind speed have been monitored from 1992 to 1996 at an expansive soil site in Nanning, a city of southern China. This paper presents the measured data and discusses the long-term field suction measurements. Measured matric suction and groung movements correlate reasonably well with seasonal changes in climate. Predictions of ground movements based on measured matric suction appear to be in close agreement with field measurement. Data obtained from this long term field monitoring can also be used to verify the theory of unsaturated flow and flux boundary conditions.
