摘　　要：海上桩基相互穿插的密集桩群施工,极易发生桩在泥面以下碰撞、已施工桩基侵占打桩船沉桩路径,导致后续桩基无法沉桩等问题。采用BIM技术建模、桩径扩大模拟和沉桩参数动态调整的方法,分析桩基碰撞与偏位容许最大误差,实现沉桩碰撞预警与防范。采用BIM 3D打印技术制作海床、桩及打桩船缩尺模型,引入水位模拟、定位装置等组合,动态、高精度模拟海上沉桩,验证桩位布置的合理性,确定切实可行的沉桩工序。When constructing interpenetrated densely packed pile foundations at sea,problems are prone to occur such as collision of piles below the mud surface,and obstacles to pile sinking by pile driving vessels caused by already constructed piles.By using BIM technology modeling,pile diameter expansion simulation,and dynamic adjustment of pile driving parameters,the maximum allowable error of pile driving collision and deviation is analyzed,and the early-warning and prevention of pile driving collision are achieved.By using BIM 3D printing technology to make scaled models of seabed,piles,and pile driving vessels,bringing in combinations of water level simulation and positioning devices,dynamically and accurately simulating offshore pile sinking,verifying the rationality of piles position layout and determining feasible pile sinking construction sequences.
