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。
Pillar around the water flow force has been the engineering design of the concern. In order to accurately measure the vertical force of vertical piles under different included angles in the model test, a new experimental device for measuring the force of piles’ water flow was designed and fabricated based on the principle of force balance. The code simulates the water flow force and verifies the measurement accuracy of the measuring device under different flow conditions. The results show that when the pile is subjected to the water flow force with different flow angles, the device has a fairly high measuring accuracy and can meet the requirements of the model test. Therefore, this method can be used to test the force of water flow in model tests of vertical piles under horizontal or oblique flow.
