The Pont del Petroli is a dismissed pier in the area of Badalona, Spain, with high historical and social value. This structure was heavily damaged in January 2020 during the storm Gloria that hit southeastern Spain with remarkable strength. The reconstruction of the pier requires the assessment and characterization of the wave loading that determined the structural failure. Therefore, a state-of-the-art Computational Fluid Dynamic (CFD) code was employed herein as an aid for a planned experimental campaign that will be carried out at the Maritime Engineering Laboratory of Universitat Politècnica de Catalunya-BarcelonaTech (LIM/UPC). The numerical model is based on Smoothed Particle Hydrodynamics (SPH) and has been employed to simulate conditions very similar to those that manifested during the storm Gloria. The high computational cost for a full 3-D simulation has been alleviated by means of inlet boundary conditions, allowing wave generation very close to the structure. Numerical results reveal forces higher than the design loads of the pier, including both self-weight and accidental loads. This demonstrates that the main failure mechanism that led to severe structural damage of the pier during the storm is related to the exceeded lateral soil resistance. To the best of the authors’ knowledge, this research represents the first known application of SPH open boundary conditions to model a real-world engineering case.

真实海浪冲击大型结构的SPH模拟

Pont del Petroli是西班牙Badalona地区的一个废弃码头,具有很高的历史和社会价值。该结构在2020年1月的Gloria风暴中以极大的强度袭击了西班牙东南部,受到严重破坏。墩的重建需要对确定结构破坏的波浪荷载进行评估和表征。因此,本文采用了最新的计算流体动力学(CFD)代码作为计划中的实验活动的辅助工具,该实验将在加泰罗尼亚理工大学巴塞罗那理工学院(LIM / UPC)的海事工程实验室进行。该数值模型基于平滑粒子流体动力学(SPH),已被用来模拟与风暴Gloria期间出现的条件非常相似的条件。完整的3D模拟的高计算成本已通过入口边界条件得以缓解,从而使波的产生非常接近结构。数值结果表明,包括自重和意外荷载在内的力均高于码头的设计荷载。这表明在暴风雨期间导致码头严重结构损坏的主要破坏机制与超出的侧向土壤阻力有关。就作者所知,该研究代表了SPH开放边界条件在实际工程案例建模中的第一个已知应用。包括自重和意外负载。这表明在暴风雨期间导致码头严重结构损坏的主要破坏机制与超出的侧向土壤阻力有关。就作者所知,该研究代表了SPH开放边界条件在实际工程案例建模中的第一个已知应用。包括自重和意外负载。这表明在暴风雨期间导致码头严重结构损坏的主要破坏机制与超出的侧向土壤阻力有关。就作者所知,该研究代表了SPH开放边界条件在实际工程案例建模中的第一个已知应用。
