Kacimov, Water exclusion from tunnel cavities spanning a water table, Journal of Hydrology, Volume 303, Issues 1-4, 1 March 2005, Pages 271-2740022-1694http://hdl.handle.net/1826/907http://dx.doi.org/10.1016/j.jhydrol.2004.08.024It is simply shown that the analysis giving the critical shape of tunnel cavities situated on a freely draining permeable substratum for water exclusion with vertical drainage through the saturated capillary fringe, can be extended to the situation where the cavities span a water table caused by an underlying water-bearing permeable substratum under pressure. It is noted that the analysis is the same for the groundwater seepage problem of water seeping to a water-bearing substratum under pressure from infinite ponded-water regions separated by a long island strip.1946 bytes22604 bytes89726 bytestext/plainapplication/pdfapplication/pdfenTunnel cavityArticle
