摘要随着海洋资源和空间的大规模开发利用,打桩区不可避免地会遇到现有的海底设施,这就需要对其进行安全评估。本文以某码头改造工程为例,采用考虑孔隙水影响的三维数值模型,研究了近岸海底环境中打桩过程中周围土体的响应和埋管的变形。数值研究分两组进行:一组是单桩,主要考虑桩管最小平面间距的影响;另一组是双桩,主要考虑桩间距的影响。
Abstract With the large-scale development and utilization of ocean resources and space, it is inevitable to encounter existing submarine facilities in pile driving areas, which necessitates a safety assessment. In this article, by referring to a wharf renovation project as a reference, the surrounding soil response and buried pipe deformation during pile driving in a near-shore submarine environment are investigated by three-dimensional (3D) numerical models that consider the pore water effect. Numerical studies are carried out in two different series: one is a case of a single pile focusing on the effect of the minimum plane distance of the pile–pipe, and the other is a case of double piles focusing on the effect of the pile spacing.
