| 摘 要： | 由于压强差的存在和桩群表面的摩擦力,水流流过桩群时将产生绕流阻力。对于单根桩的复杂水流条件下绕流阻力的理论分析尚待进一步研究,桩群的阻力计算更显复杂,限于理论计算桩群绕流阻力的复杂程度,桩群水流阻力数值模拟和物理模拟技术仍处在概化模拟阶段。为了通过实测数据辅助研究桩群阻力概化方法,依托物理模型技术、传感器发展水平、软硬件系统集成技术而提出一整套对桩群阻力测量技术的解决方案,并分析了测量结果的合理性。

| Abstract: | This paper presents the results of an experimental investigation on the effect of using piles on the flow resistance in terms of the friction factor and the different pressures.The flow resistance of pile group is more complicated than that of single pile.It is difficult to solve flow resistance of pile group theoretically at present.Based on the physical model design,sensor development,software and hardware system integration technology,this paper puts forward a set of solution for study of drag force of w... |
