摘要
为了解决主涌河水顶托现象带来的洪涝灾害,研究提出将多种防洪闸结合在一起组成一种新的水利工程,以期降低洪涝灾害带来的危害。研究首先对新的防洪闸进行模拟试验,结果显示,该防洪闸排水的准确率为98.8%,排水耗时7.8s,排水效率远高于传统方法。然后对该防洪闸的实际效果进行分析,结果显示,使用该防洪闸的区域经济损失平均降低96.7%,生态环境质量大幅度提升。以上结果表明,研究提出的防洪闸可以降低河水顶托现象造成的损失。
In order to solve the flood disaster caused by the phenomenon of the main river water being supported,a new water conservancy project is proposed by combining multiple flood control gates to reduce the harm caused by flood disasters.The study first conducted simulation experiments on the new flood control gate,and the results showed that the accuracy of the flood control gate's drainage was 98.8%,the drainage time was 7.8s,and the drainage efficiency was much higher than traditional methods.Further analysis of the actual effect of the flood control gate showed that the average economic loss in the area using the flood control gate decreased by 96.7%,and the ecological environment quality significantly improved.From the above results,it can be concluded that the flood control gate proposed in the study can reduce the losses caused by the phenomenon of river water jacking.
