根据水电建设总局隧洞规范TY—24—108—48规定,输水隧洞定型断面的尺寸应与洞宽成一定的比例关系[注一]。分五种断面型式,按流量特征值进行上述隧洞计算。这种计算需要编制流量模数K的详细图表和K与隧洞充水程度α=h/H的相对关系图。式中h——均匀流正常水深;H——隧洞断面高。现行的隧洞计算方法,根据指定的隧洞尺寸计算它的输水能力是比较简单的。然而,按这种方法解决相反的问题就复杂了。无压隧洞均匀流的水力计
According to the TY-24-108-48 stipulations of the Tunnel Authority of the General Administration of Construction and Hydropower Engineering, the dimensions of the section of the water conveyance tunnel should be proportional to the width of the hole [Note 1]. Divided into five sections, according to the flow characteristics of the tunnel calculation. This calculation requires the preparation of a detailed chart of the flow modulus K and the relative relationship between K and the degree of tunnel filling α = h / H. H - uniform flow normal depth; H - high cross-section of the tunnel. The current tunnel calculation method, according to the specified tunnel size to calculate its water delivery capacity is relatively simple. However, solving the opposite problem in this way is complicated. No pressure tunnel uniform flow hydraulic meter
