托帕水库整体水工模型试验研究

Experimental study on integral hydraulic model of Tuopa Reservoir

为了研究各泄水建筑物布置的合理性、泄洪冲沙洞和溢洪洞体型的优劣及下游消能情况,建造了新疆克州恰克玛克河托帕水库整体水工模型。通过模型试验,在施工导流期和正常运行期不同试验工况下,对泄洪冲沙洞和溢洪洞进出口体型、泄流能力、水流流态、流速分布、消能防冲、空蚀空化等进行了系统研究,并根据试验结果以及下游消能、河道冲刷情况,提出了进出口体型相应的修改建议。此项研究可为托帕水库设计方案比选提供技术参考。

The integral hydraulic model of Xinjiang Qiakemake River Tuopa Reservoir is built in order to study the layout rationality of all drainage buildings,the advantages and disadvantages of the spillway sand flushing tunnel and the overflow tunnel shape,and the downstream energy dissipation situation.The inlet and outlet shapes,discharge capacity,water flow regime,velocity distribution,energy dissipation impingement,cavitation and other aspects of flood discharge scour tunnels and spillway tunnels are systematically studied through the model test during the construction diversion period and normal operation period under different test conditions.Corresponding revision suggestions of inlet and outlet shapes are proposed according to test results,downstream energy dissipation,the river channel scour situation.The research can provide technical reference for comparison and selection of design units of Tuopa Reservoir.
