| 摘 要： | 通过模型试验寻找原方案中的设计缺陷,对沉沙槽的结构进行优化,改进了束水墙方案以消除原方案对取水防沙的不利影响,并通过模型试验对比了最终效果。试验证明,被淹没的束水墙方案可以明显增加沉沙槽内水流的扰动,有效提高沉沙槽内水流的挟沙能力,改进拉沙效果。

| Abstract: | The model tests were performed to search the design defects of the original scheme.The structure of the grit channel was optimized.It was improved to eliminate the adverse impact on the water diversion and sediment prevention in the original scheme.Based on the model tests,the final results were compared.A conclusion is drawn that the guide wall submerged by water can obviously improve the turbulence in the grit channel so as to strengthen the sediment transport capacity of water and consequently improve scour capacity. |
