In order to optimize the perpetuation tensioning tonnage of prestressed pier anchor wire of goupitan arch dam, first the scheme contrast method is adopted to define the perpetuation tensioning tonnage combination of the primary and secondary anchor wire, but the optimization result is that the pull - anchor coefficient is too big ; then the body form of the pier is optimized ; finally the anchor wire perpetuation tensioning tonnage is optimized by using ansys optimization design module based on parametric fem, the optimization result is acceptable and the pull - anchor coefficient is lowered down
摘要為優化構皮灘拱壩中孔預應力閘墩錨索永存張拉噸位，首先採用方案優選的方法確定主次錨索永存張拉噸位組合，但優選結果拉錨系數偏大，再對閘墩體型進行優化，然後採用基於參數化有限元的ansys優化設計模塊對主次錨索永存張拉噸位進行優化，優化結果滿足應力控制要求，降低了拉錨系數。 -
