This study evaluates a novel biopolymer-based material reinforcement method. A real-scale experiment minimizing flood disasters and economic losses incurred by the collapse of river levees due to overtopping was conducted. At the Andong River Experiment Center, lateral overflow was reproduced to induce levee collapse using sand, reinforced novel materials, and vegetation levees represented as cases 1, 2, and 3, respectively. The flow in the upstream and downstream areas was measured, and fluctuations in the lateral overflow discharge were calculated using an acoustic Doppler current profiler. To quantitatively verify the performance of this method, the collapse delay effect based on the surface loss rate of the levee slope was analyzed using image pixel analysis and three-dimensional point cloud modeling. Comparing the collapse delay effect of the new-material levee with that of the non-reinforced levees, we found a time delay of approximately 2.7–7 times from the occurrence of overtopping via the lateral flow to the end of the test. These results indicate that we can secure time for emergency repairs and operations by reinforcing the levee surface using the material proposed in this study. These research findings are expected to provide the basis for the proper design and construction of river levees.

使用新型生物聚合物的表面加固堤防的抗侵蚀性能通过真实规模的漫天实验进行研究

本研究评估了一种新型的基于生物聚合物的材料增强方法。进行了实际规模的试验，最大限度地减少洪水泛滥造成的河堤坍塌造成的洪水灾害和经济损失。在安东河实验中心，利用沙子、加筋新材料和植被堤坝，分别以案例1、2和3表示，再现了侧向溢流导致堤坝坍塌。测量了上游和下游区域的流量，并使用声学多普勒电流剖面仪计算了横向溢流流量的波动。为了定量验证该方法的性能，利用图像像素分析和三维点云建模分析了基于堤岸边坡表面损失率的坍塌延迟效应。对比新材料堤防与非加筋堤防的坍塌延迟效应，我们发现从侧流发生漫溢到试验结束的时间延迟约为2.7-7倍。这些结果表明，我们可以通过使用本研究中提出的材料加固堤坝表面来确保紧急维修和操作的时间。这些研究成果有望为河堤的正确设计和建设提供基础。
