Seepage is ubiquitous during tunneling in areas with high groundwater tables. The ground settlement trough on a single tunnel well described by Peck’s formula, but it cannot reflect the caused seepage. In this paper, assuming that inside and outside one-dimensional steady-state seepage condition, drainage model of was established. Based principle dynamics, flow calculation formula derived, dewa...

Interpolated contour maps drawn for aluminum, copper and molybdenum in downstream monitoring boreholes of water dam in Miduk Copper Complex and the values of pH, redox potential (Eh) and distance from water dam indicate different trends of variation and behavior of these three elements in downward groundwater resources. As these maps exhibit, aluminum is dominant in the most alkaline (pH = 9-11...

In China, for the limitation of land, many buildings intending to utilize ground source heat pump systems install “single-well” systems, which drill only one well for both the pumping and reinjection of the groundwater. A model of groundwater seepage and heat transfer for single-well ground source heat pump systems has been established and validated against the experiment conducted in Denmark. ...

upstream blankets, drains and cutoff walls are considered as effective measures to reduce seepage, uplift pressure and exit gradient under the foundation of hydraulic structures. to investigate the effectiveness of these measures, individually or in accordance with others, a large number of experiments were carried out on a laboratory model. to extend the investigation for unlimited arrangement...

A hydromechanical envelope that governs the onset of soil erosion by seepage-induced internal instability is examined with reference to theoretical and laboratory stress-gradient paths for one-dimensional upward downward seepage flow. The method validated from permeameter test results on glass ballotini. Using theory, analysis a database 22 gradations establishes semi-empirical relation between...
