摘要
在工程设计中会遇到大范围潜堤及透浪式建筑物条件下的泊稳问题,物理模型试验受场地限制难以实施,尚无有效的解决实际工程问题的平面二维数值模拟方法。文章以某港为例,采用断面物理模型试验和数学模型试验相结合的方法,将断面物理模型试验实测的透射系数作为数学模型的输入条件,通过在数学模型中设置虚拟潜堤的方法有效模拟了潜堤的透射和反射。该方法为解决潜堤及透浪式建筑物的越浪与透浪问题,提出了一种有效的数、物模相结合的数值模拟方法,为港口总平面设计提供了科学的研究依据。
In the engineering research for large scale of submerged jetty or permeable works, plane physical model is difficult to implement for the limit of space, and there are no applicable plane 2D numerical simulation method can be used to solve practical engineering problems. This paper takes one port as an example and developed a method that combined sectional model with numerical experiments, takes the transmission coefficient measured by sectional physical model test as the initial condition for numerical model test, through the method for setting virtual submerged breakwater in mathematical model to effectively simulate the transmission and reflection of submerged breakwater. This method brings forward an effective numerical simulation method that combines physical and numerical model together, and provides scientific research basis for general plan layout design.
