THE OPTIMUM LOCATION OF CONCRETE SHEET PILES UNDER HYDRAULIC STRUCTURE AFFECTED THE SEEPAGE WATER PRESSURE USING ANSYS PROGRAM
The problem of water seeping through the earth dams or under concrete structure is regarded one of the main reasons of the structures’ failure. This may be due to the failure in soil layer on which the hydraulic structure is constructed or due to the water pressure resulting from a difference in the level of the upstream and downstream. In previous studies have found that the use of concrete sheet piles under the dams is one of the effective solutions to control the seepage of water under structures, this study considers that control of this problem is by using sheet piles. The 2-D F.E. model ANYSIS Program, has been used to analyze the effect of the optimum location of concrete sheet piles affected on seepage water pressure underneath hydraulic structures, when the stability against seepage water pressure against piping were calculated in different cases. The results showed the water pressure reduce, when the sheet pile downstream is used at 60° and depth 6m.
