Study on the Influence of Variable Water Temperature on Seepage in Single Fracture

Abstract:

approximate analysis formula for the water flow of single fracture and variable water temperature has been deduced considering the impact of water temperature to rock fracture seepage. Following conclusions were drawn: (1) The water head and the hydraulic gradient in single-fissure have nonlinear relation. Seepage curve was convex curve if water flows from higher temperature areas to lower temperature area. On this condition, the water head slants low under liner seepage simplification. On the contrary, Seepage curve is convex curve if water flows from lower temperature areas to higher temperature areas, and the water head slants high. (2) In a single fracture, the hydraulic gradient is smaller in the higher temperature zone and is larger in the lower temperature zone. The higher the mean water temperature of fracture was, and the faster the flow velocity was.
