升船机船厢出入水中间渠道内水力特性试验

Study on hydraulic characteristics for ship chamber falling and rising from water in the intermediate channel

船厢出入水在中间渠道内产生非恒定波流,属于浅水长波,在其未反射之前具有引航道的水力特性;反射以后形成往复的振荡波;浅水长波在传播的过程中,在某种条件下也有短波现象。试验研究了船厢不同出入水速度、渠道不同宽度和水深时与渠道内水力要素的关系,同时分析了渠道内的通航条件。

The wave motion belongs to the shallow water wave for ship chamber falling and rising from water in the intermediate channel, which has the hydraulic characteristics of the approach channel before reflecting, and take on fluctuating characteristics after reflecting. Short - wave will be shaped in certain conditions when the shallow water wave propagating forward. The relationships among the different velocity of the ship chamber falling and rising, the different width and water depth of the intermediate channel and the hydraulic characteristics in the intermediate channel are studied, and the navigation conditions in the intermediate channel are also analyzed.
