罗源湾2×5万吨级码头前板桩结构变形计算

Calculation for deformation of frontal sheet piles of 2×50,000 DWT wharf in Luoyuanwan Bay

罗源湾2×5万吨级泊位采用前板桩高桩码头结构,这是一种较为复杂的混合结构。为了确保码头结构可靠性,前板桩结构变形计算采用了空间杆系有限元和平面应变有限元两种方法。介绍了两种计算方法的关键参数取值和前板桩变形计算结果,并将计算结果与变形实测数据进行了比较,从而验证了了两种计算方法关键参数取值的合理性。

The marine structure of 2×50,000 DWT wharf in Luoyuanwan Bay adopts a high piled structure with frontal sheet piles,which is a kind of complicate hybrid structure.In order to guarantee the structure s reliability,space member system and plane strain finite element model is applied for the computing the deformation of the frontal sheet pile.The key parameter values of the two calculation methods and the calculation results of the frontal sheet pile deformation are introduced,and the calculation results are compared with the actual deformation data,which verifies the rationality of the key parameters of the two calculation methods.
