Finite Element Analysis for Side Pier in Overflow Dam of Zhuzhou Navigation-power Junction

In the design work of dams,the overflow pier is a significant project only next to the dam body.For this kind of structure,using a common bar mechanics approach is difficult to obtain satisfactory results,so the finite element analysis software ANSYS is used to check and calculate the structure stress at the normal water level and check water level for the pier 25# in the overflow dam of Zhuzhou navigation-power junction.Through the calculation,it is found that under normal water level condition,and because of the gate thrust,water pressure and active earth pressure,there appears the tensile stress concentration at the bracket,whereas in the dorsal surface,the tensile stress area appears at the corner of the upstream face and water face of the pier’s back side.The distribution law of stress and displacement on the pier could be summarized through the analyses,which could provide some bases for the reinforcing,and verify the rationality of the structural design.
