摘要
陡坡导流隧洞内水流条件较缓坡隧洞复杂,进口漩涡、洞身段明满流交替、出口消能防冲等问题较为突出,以马来西亚沐若水电站导流隧洞为例,配合水工模型试验,对隧洞断面形式、进出口体型、底坡衔接及出口消能防冲形式进行了研究,从结构设计上有效解决了上述水力学问题可能对导流隧洞运行造成的影响。
The flow condition of the diversion tunnel with steep slope is more complicated than that of a gentle slope.The free surface flow and pressured flow alternate in the vortex section in the inlet and the tunnel section and the problem of energy dissipation and erosion prevention are serious.Taking the diversion tunnel of Murum Hydropower Station in Malaysia as an example,combining with the hydraulic model,the cross section form of the tunnel,body type of the inlet and outlet,the bottom slope connection form and energy dissipation and erosion prevention forms in the inlet and outlet were studied.In the view of structural design,the influence of the above hydraulic problems on the diversion tunnel was eliminated,so the operation safety of the diversion tunnel was ensured.
