| 摘 要： | 低水头闸坝工程的一个普遍水力学问题是低佛氏数水流的消能防冲，其特点是消能率低，为达到较好的消能效果，常常要在消力池加一些辅助消能工程。结合青海省引大济湟调水总干渠闸坝工程的水工模型试验，将T型墩置于海漫浆砌石段，有效的削弱了水流的余能。通过试验可以看出海漫段设置T型墩对低佛氏数的泄水建筑物有较好的消能作用。

| Abstract: | In low water head hydraulic constructions,a common hydraulic problem is energy dissipation for small Froude number water flow because the energy dissipation is less efficient.Some supplementary structures are generally applied in dissipation pool to get better result of energy dissipation.Based on hydraulic model experiment of the Trunk Canal in the Project of Water Divertion from the Datong River to Huang River in Qinghai Province,through application of T-shaped pier to apron extension,the remaining energy of the water flow is abated effectively.The results of the hydraulic model experiment show that application of T-shaped pier in the apron extension can effectively abate the remaining energy in the discharge structures of small Froude number. |
