Permeable pavements play an effective role in reducing runoff by decreasing the impermeable area. But, conventional permeable pavements suffer disadvantages such as low resistance. To address this, the 'high-strength clogging-resistant permeable pavement (CRP)' has been developed. The present study aimed to evaluate the performance of the CRP model with varying percentages of coverage (A) of 25, 50, and 100%, slopes (S) of 1, 3, and 5%, as well as rainfall intensities (I) of 45, 55, 70, 90, 170, and 200 mm/h. Based on the results, there was an increase in A from 50 to 100% at I = 90 mm/h, decreased runoff coefficient (C) of 18, 15, and 13% at S of 1, 3, and 5%, respectively. At the same I, increasing S from 1 to 5% increased the C coefficient in A of 0, 25, 50, and 100% by 3, 31, 32, and 39%, respectively. Due to the ever-increasing urbanization and the subsequent increase in impervious areas, the risk of severe floods has greatly increased. Therefore, providing solutions such as the CRP model can help reduce flood risks in urban areas. The findings of this research can be used as a guide in the design of high-strength clogging-resistant permeable pavements in urban areas.
透水路面通过减少不透水面积，在减少径流量方面发挥了有效作用。但是，传统的透水路面存在阻力低等缺点。针对这一问题，开发了“高强度抗堵塞透水路面（CRP）”。本研究旨在评估 CRP 模型在不同覆盖率（A）为 25%、50%和 100%、坡度（S）为 1%、3%和 5%以及雨强（I）为 45mm/h、55mm/h、70mm/h、90mm/h、170mm/h 和 200mm/h 下的性能。结果表明，在 I = 90mm/h 时，A 从 50%增加到 100%，径流系数（C）分别减少了 18%、15%和 13%，S 分别为 1%、3%和 5%。在相同的 I 下，S 从 1%增加到 5%，A 分别为 0%、25%、50%和 100%，C 系数分别增加了 3%、31%、32%和 39%。由于城市化进程的不断推进和不透水面积的增加，城市发生严重洪灾的风险大大增加。因此，提供 CRP 模型等解决方案可以帮助降低城市的洪灾风险。本研究的结果可以作为城市高强度抗堵塞透水路面设计的指南。
