In order to study whether the original design flow can be met after the lining scheme of sections of a long distance non-pressure diversion tunnel is changed, the flow capacity of typical sections of the tunnel was analyzed by model test and theoretical calculation. There are 4 tunnel diameters and 2 roughness in the typical section of the tunnel. In order to meet the conditions of similar resistance, different materials were compared and tested, and the roughness was determined. Through testing and analyzing the flow capacity and flow characteristics at three operating conditions, it is concluded that the flow can be safely passed under operating condition 1, and the clearance margin of some tunnel sections under operating condition 2 is insufficient, with the minimum margin of 14.39%. Most tunnel sections under operating condition 3 do not meet the safety flow. Comparing the test and theoretical calculation, the results of the two are relatively close, and the test value is relatively safe, which can provide a theoretical basis for the construction and operation of the project.

为研究某长距离无压引水隧洞部分洞段改变衬砌方案后能否满足原设计流量的问题,采用模型试验和理论计算的方法分析了该隧洞典型区段的过流能力。该隧洞典型区段共有4种洞径,2种糙率,为满足阻力相似条件,对比测试不同材料,并进行糙率率定。对3种运行工况的过流能力及水流特性进行测试与分析,得出工况1可安全过流,工况2部分洞段净空余幅不足,最小余幅值为14.39%,工况3大部分洞段不满足安全过流。对比试验值与理论计算值,二者结果较接近,且试验值偏安全,可为该工程施工、运行提供理论依据。

为研究某长距离无压引水隧洞部分洞段改变衬砌方案后能否满足原设计流量的问题,采用模型试验和理论计算的方法分析了该隧洞典型区段的过流能力。该隧洞典型区段共有4种洞径,2种糙率,为满足阻力相似条件,对比测试不同材料,并进行糙率率定。对3种运行工况的过流能力及水流特性进行测试与分析,得出工况1可安全过流,工况2部分洞段净空余幅不足,最小余幅值为14.39%,工况3大部分洞段不满足安全过流。对比试验值与理论计算值,二者结果较接近,且试验值偏安全,可为该工程施工、运行提供理论依据。

In order to study whether the original design flow can be met after the lining scheme of sections of a long distance non-pressure diversion tunnel is changed, the flow capacity of typical sections of the tunnel was analyzed by model test and theoretical calculation. There are 4 tunnel diameters and 2 roughness in the typical section of the tunnel. In order to meet the conditions of similar resistance, different materials were compared and tested, and the roughness was determined. Through testing and analyzing the flow capacity and flow characteristics at three operating conditions, it is concluded that the flow can be safely passed under operating condition 1, and the clearance margin of some tunnel sections under operating condition 2 is insufficient, with the minimum margin of 14.39%. Most tunnel sections under operating condition 3 do not meet the safety flow. Comparing the test and theoretical calculation, the results of the two are relatively close, and the test value is relatively safe, which can provide a theoretical basis for the construction and operation of the project.
