摘　　要：东海大桥PM445号桥墩墩位处基岩裸露,岩面高低起伏,岩石强度高,水流流速大,下部桩基施工难度大。设计根据现场情况对PM445号桥墩进行了优化,较好地满足了工期要求,为东海大桥早日建成做出了贡献。At the location of Pier PM445 of Donghai Bridge, the rock bed is uncovered, rock surface is wavy, rock strength is great and water current is swift, the construction of the substructure pile foundation of the Bridge there is difficult. In the design, the Pier PM445 is thus optimized in accordance with the conditions at the Pier location, the construction schedule requirement for the pier is fairly well satisfied and contributions have been made to an earlier completion of the Bridge.
