【摘要】 根据常张高速溇水大桥墩柱的水工环境,对溇水大桥受流水冲刷影响较为严重的墩柱进行流-固耦合分析。墩身应力计算分布结果反应了墩身受冲刷影响的大小。研究表明墩柱系中各墩受冲刷作用力因各墩位置而异,墩身受到的动水压强和墩周流场情况共同决定墩身所受的冲刷程度。更多还原

【Abstract】 According to the hydraulic environment of Loushui bridge foundation,modeling and FSI simulation to the pile column which scoured more seriously by the flowing water. The stress distribution results reflects it’s scouring situation. Studies have shown that the degree of influence depends on these piles’ position,and believed piles’ scouring degree is co-decided by both the dynamic water pressure and water flows field around piles.更多还原
