A study of the distribution of temperature-humidity and vapor-liquid transformation in the water vapor field of fractured rock mass: a case study in the Jinping Mountain of Yiyang county in Henan

Water vapour field is a general term used to describe the temperature in the unsaturated water zone of the fractured rock mass and the temporal distribution of water and vapor. Some key questions have not been examined until now such as the distribution of temperature-humidity in the water vapor field of the fractured rock mass as well as the laws of vapor-liquid transformation in the water vapor field. The Jinping Mountain of Yiyang county is taken as an case study in this paper and the distribution of temperature-humidity as well as the laws of vapor-liquid transformation in the water vapor field are analyzed using the measured temperature and moisture at all seasons in the long-term monitoring holes. The research results show that (1) spring and summer are the main periods for the increase in water and heat in the fractured rock, when the humiture in the water vapor field of fractured rock gradually raises from the inside out. Distribution range of the internal condensation water in fractured rock is large and its external counterpart on the boundary is about 20 cm. (2) Conversely, water and heat in the fractured rock decrease and the humiture gradually reduces from the inside out in autumn and winter. The nternal water distribution range of fractured rock is small while that on the outside ranges from 50 to 200 cm.
