摘要
针对一些泄水建筑物低水头、低佛氏数的特点,结合龙口水利枢纽工程实际进行了模型试验,通过对消能工的修改和几种方案的试验比较,研究了低水头出流的消能方式,考虑到主流区流速偏大,对水流可能对下游河床造成的局部冲刷进行动床试验,综合试验成果,提出了可行的消能防冲措施。
According to the characteristics of some discharge structures with low water head and low Froude numbers, the model test was done on tne basis of combining the practical condition of Longkou Water Control Project.The dissipation method with low water head was analyzed through the modeification of energy dissipator and the comparision of tests for serval kinds of schemes. Copnsidering that the flow speed is so fast in the main flow area, the movable-bed test was conducted for local scouring caused by downstream river bed of water flow and on the basis of this, the feasible dissipation and erosion-control measures were put foreward in the comprehensive test results.
