波浪作用是影响管袋筑坝的最主要外部荷载,关系到管袋结构的安全与稳定。为了解管袋堤坝在波浪作用下的波浪压力,基于流体力学计算软件FLUENT建立数值水槽模型,通过设定不同的边界条件,采用源造波法模拟不同波高、周期、水深、坡率下波浪与管袋坝面的相互作用,计算管袋受力和波陡、坡率之间的关系,并拟合相应关系曲线得到管袋坝的受力和波陡、坡率之间的函数关系式。结果表明,该方法的结果与物理试验过程中获得的规律相符,具有一定的实用性。
The wave effect is the most important external load that affects the construction of the pipe bag and relates to the safety and stability of the pipe bag structure. In order to understand the wave pressure of tube embankment dam under the action of waves, a numerical reservoir model was established based on fluid dynamics calculation software FLUENT. By setting different boundary conditions, the source wave method was used to simulate the waves with different wave height, period, water depth, The interaction between pipe and bag surface, the relationship between the force and the steepness and the slope of the pipe, the relation between the stress and the steepness and slope of the pipe-bag dam are obtained. The result shows that the result of this method agrees with the rule obtained in the process of physical experiment and has certain practicality.
