盘海特大桥承台钢板桩围堰设计计算

摘要

以盘营高铁客运专线盘海特大桥水下承台钢板桩围堰施工实例为背景,介绍了钢板桩围堰设计计算的理论与方法,并进行了钢板桩围堰结构验算、反弯点及最小入土深度计算,从而验证了施工方案的合理性。%Based on the steel sheet pile cofferdam underwater platform of Panhai super large Bridge in Pan-Ying high-speed railway passenger dedicated line the theory and method of design and calculation of the steel sheet pile cofferdam is introduced.Moreover,the checking computations of the steel sheet pile cofferdam structure,the calculation of the inflection point and the least embedded depth into soil are afforded,thus it verifies the rationality of the construction scheme.
