在设计高水头泄水建筑物时,综合实测资料对设计高水头泄水建筑物具有重要的意义。本文研究影响下游河床和河岸变形的水工建筑物的参数。图1示出计算图式;表I就两类水利枢纽——一类下游宽阔,一类位于窄小狭谷中(拱坝)——列出某些几何参数、水力学参数和冲刷坑参数(最大深度冲刷坑的资料较为完整)。
In the design of high head drain structures, the comprehensive survey data is of great significance to the design of high head drain structures. This paper studies the parameters of hydraulic structures that affect the deformation of the downstream riverbed and bank. Figure 1 shows the calculation scheme. Table I lists some of the geometric parameters, hydraulic parameters and scouring pit parameters for two types of water control projects - one broad and one downstream in narrow valleys (arch dams) The maximum depth of scour pit information is more complete).
