| 摘 要： | 为实现增加糙率降低近底流速的目的,用废旧轮胎制作海漫表面的加糙体。通过室内水工模型试验,对加糙轮胎的数量、布置形式、相对糙度等影响因素进行比较研究,得到利用废旧轮胎进行海漫加糙的最佳方案。试验结果表明,用废旧轮胎加糙可使近底流速降低50%。经现场原型试验,利用废旧轮胎加糙,闸下冲坑深度平均减少75.7%,冲坑面积减少19.3%,减冲效果明显。应用表明,利用废旧轮胎加糙减冲是切实可行的。

| Abstract: | Scrap tires were acted as apron carriers to improve the roughness and decrease the near-bottom velocity.Based on laboratory hydraulic model tests,a comparative analysis was performed of some influencing factors on the effect of energy dissipation and erosion control,including the number,layout pattern and relative roughness of scrap tires,and an optimal scheme of scrap tires for improvement of the apron roughness was obtained.The test result shows that the adoption of scrap tires decreases the near-bottom velocity by 50%,and reduces the depth and area of erosion under sluice by 75.7% and 19.3%,respectively.Therefore,the effect of erosion control is evident,and the technique is feasible. |
