| 中文摘要: |
| 桩柱的绕流水流作用力一直是工程设计中所关注的问题。为了精确地测量模型试验中竖直桩柱在不同来流夹角下的水流作用力,基于力的平衡原理,设计并制作了一种新的桩柱水流作用力试验测量装置,并采用标准砝码模拟水流作用力,验证了该测量装置在不同来流工况下的测量精度。结果表明：桩柱受不同来流夹角的水流作用力时,该装置都具有相当高的测量精度,可满足模型试验要求。因此,该测量方法可用于竖直桩柱在水平或斜向水流作用下模型试验中水流作用力的试验研究。 |

| Great attention has been paid on the hydrodynamic forces acting on piles in engineering design. In order to accurately measure hydrodynamic force acting on a vertical pile, when water flow passes it with different incidence angles, a new device measuring the force in laboratory was developed based on the principle of force balance. Under the condition of different incidence angles, its measuring accuracy was tested by using standard weights to simulate hydrodynamic force. Results show that the new device has high accuracy and can meet the test requirements in those situations Therefore, this new developed device can be practically used to measure hydrodynamic force acting on a vertical pile in laboratory. |
