墩身竖向预应力损失理论与试验研究

Theoretical and experimental study on vertical prestressing loss of pier

依托港珠澳大桥埋置式承台足尺模型工艺试验项目,采用理论计算分析与试验监测相结合的办法对墩身竖向预应力损失展开研究,提出减小墩身竖向预应力损失的措施,为港珠澳大桥主体工程建设关键施工参数的确定提供依据。

Relying on the full-scale model test of embedded pile capping for the Hongkong-Zhuhai-Macao Bridge, we used the method combining theoretical calculation analysis with the tests to study the vertical prestressing loss of the pier. The measure to reduce the vertical prestressing loss is put forward to provide a basic for key construction parameters of the main works of the Hongkong-Zhuhai-Macao Bridge.
