基于颗粒物堆积的混凝土路面透水砖参数模拟

Parameter Simulation of Permeable Brick in Concrete Pavement Based on Particle Accumulation

传统混凝土路面透水砖堵塞模拟方法由于计算环节设定较为落后,忽略了对雨水流体力学数值的计算,导致模拟结果与实际情况出现较大偏差,数值模拟精度较低。针对上述问题,设计雨季混凝土路面透水砖堵塞数值模拟方法。应用颗粒物堆积模型法构建混凝土路面透水砖物理模型。根据质量守恒定律、牛顿第二动力定律以及能量传输定律,计算雨水流体力学数值使用雷诺数体现水流状态以及悬浮物吸附函数数据,完成透水砖堵塞数值模拟。仿真环节分析此方法性能,实验结果证实上述方法的应用精度较高,研究方法得到的模拟结果更可靠。

The traditional simulation method of permeable brick blockage in concrete pavement ignores the numerical calculation of rainwater hydrodynamics,resulting in the simulation results inconsistent with reality and low numerical simulation accuracy.Therefore,a numerical simulation method of permeable brick blockage of concrete pavement in the rainy season is designed in this paper.Firstly,the particle accumulation model method was introduced to construct the physical model of permeable brick in concrete pavement.Secondly,based on the law of mass conservation,Newton’s second dynamic law and energy transfer law,the numerical value of rainwater hydrodynamics was calculated,and then the data of water flow state and suspended matter adsorption function were characterized by the Reynolds number.Finally,the numerical simulation of permeable brick blockage was completed.The experimental results show that the method has reliable simulation results and high application accuracy.
