在湖南、四川丘陵山区的小型船闸,有不少采用短廊道垂直竖井的输水方式,该类船闸平面尺寸不大,但有较高的帷墙。该型式的输水特点是廊道水流由不连续到连续。水流进入闸室的能量如何正确计算,与消能工设计(消能室体积大小,镇静段长度的确定),船只停泊条件有关,并涉及到工程造价。今根据船闸水力学试验研究,将我们的看法阐述如下。
In Hunan, the small locks in the mountainous areas of Sichuan have many ways of transporting water with vertical shafts in short corridors. The size of such locks is not large but has a high curtain wall. This type of water delivery is characterized by corridor water flow from discontinuous to continuous. How to calculate the energy of the water flow into the lock chamber is related to the design of energy dissipater (the size of the energy dissipating chamber and the length of the calm section), the mooring conditions of the vessel, and the project cost. According to the ship lock hydraulics test research, we will set out as follows.
