I am designing an underground circular tank for water retention. Its a big storm water tank. It has 25 meter diameter and 30 meter deep. The outer strata is rock (qu=20000 to 25000 KN/Sqm), its lime stone. Its dry density is almost as of hardened concrete, i.e 2.46 MN/m3. Water table is also not...
