Through checking computations, it was shown that the analogue accuracy of the model was quite high, which can provide important basis for scientific decision - making on engineering measures. through analogue calculation and analysis of many regulation schemes, it was shown that combining the diversion weir works with the bed fixing works at the south branch is reasonable and feasible in the implementation of loushuikouzi river regulation works. in addition, it is suggested that the bed fixing works at the south branch should adopt the improved compound section scheme
經對多個整治方案的模擬計算與分析,表明漏水口子河道整治採用分流魚嘴工程和南汊固床工程相結合的整治工程措施是合理可行的,通過模型計算研究還提出了南汊固床工程採用復式斷面形式的改進方案建議,該方案保證了南汊枯期通航和不斷流,而且對南汊及撫遠鎮的保護具有正面作用。A 2 - d hydrodynamic - numerical model was applied to typical rocky rapids called jiyutan by comparing different computational models. based on the comparison of different schemes, the change of the discharge and the flow current in a branch were analyzed, and the relationship between the flow condition and excavation area, scope as well as mode was discussed, the conclusions show : ( 1 ) in a branching rocky rapids, the velocity may be reduced and flow condition can be improved by excavating one channel partly
本文在對各種數學模型比較的基礎上,應用二維水動力數學模型研究典型石質汊流灘? ?廣西潯江鯽魚灘航道整治工程方案,通過各方案計算結果比較,分析了不同汊道的開挖及汊道內不同開挖面積、開挖范圍以及開挖方式所引起的分流比及工程區域航道水力條件的變化規律,研究結果表明: ( 1 )對于石質汊流灘來說,在某一汊道通過局部開挖河槽,擴大過水斷面面積,可以達到降低工程段流速、改善局部水流條件的目的。Excavating riverbeds in one channel may not only reduce the velocity area in some areas but also increase the velocity in other areas by increasing flow rate in this channel without correspondent changes in riverbeds of rocky rapids. in result, the velocity in waterway may be increased instead of be reduced, the flow condition may also be deteriorated. thus, which branch should be excavated and how to excavate in improving the flow condition of the branch should be further explored
但在分汊河道內,情況較為復雜,在一汊河道內採取開挖措施后,雖然其過水斷面有所增加,局部流速相應降低,但是由於工程后,汊道的分流比將會相應變化,而石質河床一般無法通過沖淤變化以適應水流條件的改變,因此,航道內工程處的流速可能降低,也可能不降反而有所增加,惡化了航道的水流條件。( 3 ) in excavation channel, the velocity in engineering area may be reduced, but the velocity in other areas of this channel may be increased and the flow condition may be deteriorated as a result of the increase of flow rate in this channel. thus, it should be discussed and studied before engineering practice
( 3 )在汊道的開挖中,工程區域的局部流速可能有所下降,但因分流比有所增加,可能導致其餘部分河段的流速有所增加,惡化航行水流條件,因此在工程前需要進行充分的論證和深入的研究。分享友人
