( 4 ) the dike breach risk of the south bank is relative higher in wandering reaches. ( 5 ) the dike breach risk of the north bank is higher than the south bank in winding reaches. simultaneously, the evaluation results manifest that the evaluation indexes system established from the locomotion of incoming water and sediment load, the regional crustal stability, the evolvement of river regime and the stability of river dikes, can reflect the actual situation of hang river in the lower yellow river more fully
評價結果同時表明，從水沙運動、區域地殼穩定性、河勢演變和堤防穩定性4個方面建立評價指標體系，能夠更加全面的反映黃河下游懸河的實際情況;運用多層次模糊綜合評判法能夠較好地解決影響因素眾多、作用機制復雜的懸河決溢風險問題;運用gis技術強大的空間分析功能，使黃河下游懸河不同空間位置的決溢風險得到了量化，可以客觀地反映黃河下遊河道不同空間位置決溢風險的差別，對于指導防洪和河道治理的實踐具有重要的現實意義。 -
Based on analysis of hang river ' s actuality in the lower yellow river and researches related with evaluation of dike breach risk, it is put forward that the influencing factors of hang river dike beach risk in the lower yellow river should involve 4 aspects, the locomotion of incoming water and sediment load, the regional crustal stability, the evolvement of river regime and the stability of river dikes. the evaluation indexes system of hang river dike breach risk and uniform synthetic model are established from the 4 aspects. with the support of gis technology, the evaluation indexes system and the model of multi - hierarchical fuzzy synthetic judgment are applied to estimating the dike beach risk of hang river in the lower yellow river under different flood conditions
在對黃河下游懸河現狀、決溢風險評價有關研究進行分析的基礎上，本文提出黃河下游懸河決溢風險的影響因素應當包含水沙運動、區域地殼穩定性、河勢演變和堤防穩定性4個方面，並從這4個方面建立了黃河下游懸河決溢風險評價的指標體系和統一的綜合評價模型;在gis技術的支持下，運用評價指標體系和多層次模糊綜合評判模型，對不同洪水情景下黃河下游懸河的決溢風險狀況進行了評價。 -
By the analysis and study, it is showed that : 1 ) the lower weihe river main channel was at a balanceable state between aggradation and degradation and floodplain of the lower weihe river is a tiny aggradation state before the construction of the sanmenxia dam ; 2 ) the severe aggradation of the lower weihe river bed is mainly caused by the increasing riverbed elevation at tongguan after the construction of the sanmenxia dam ; 3 ) the main reason leading to the increasing riverbed elevation at tongguan is the unreasonable operation of the sanmenxia reservoir ; 4 ) the rate of the riverbed aggradation at tongguan reach and the lower weihe river reach are speeded by adverse condition of incoming water and sediment recently
然後以實測資料為基礎分析研究了三門峽建庫前後潼關高程的變化規律以及渭河下遊河道的沖淤演變規律，分析研究表明：建庫前渭河下游主槽處于動態沖淤平衡狀態，灘地處于微淤狀態；建庫后，渭河下遊河道發生嚴重淤積主要是由於潼關高程的抬升造成的；潼關高程的抬升主要是由於三門峽水庫的不合理運用造成的，近期不利的水沙條件加劇了潼關河床的抬升速度和渭河下游的淤積。 -
In this paper, the deposition evolution process in qtx reservoir are studied, the incoming water and sediment, the operation data, and the time and space distribution of longitudinal and lateral sedimentation in reservoir are analyzed in detail, and the longitudinal scouring and sedimentation and lateral deformation law in reservoir tidal flat and mainstream under different operation way are summarized in every operation period
本文以黃河青銅峽水利水電樞紐工程水庫淤積演變過程為研究對象，對青銅峽水庫來水來沙組成、水庫運行資料、水庫縱橫向泥沙淤積時空分佈等進行了較詳細的分析，總結了青銅峽水庫各個運行時期不同運行方式下水庫灘槽縱向沖淤和橫向變形規律。 -
This paper deals with the characteristics of incoming water and sediment and changes of tongguan elevation since sanmenxia reservoir began its storing clear water and releasing sediment operation mode
本文闡述了三門峽水庫「蓄清排渾」運用以來入庫水沙的特性和潼關高程的變化，對潼關高程非汛期升高、汛期降低的基本規律進行了分析。 -
Abstract : by analyzing the changes of incoming water and sediment in the lower weihe river, in allusion to the question of flood discharge capacity being not enough, control project being short, river pattern can ? t being controlled and the management being loose etc, advise to increase the investment, consummate the measures of flood prevention engineering and non - engineering. strengthen the management, consolidate the consciousness of flood prevention and disaster alleviation, in order to raise recent ability of flood prevention in the lower weihe river
文摘:通過對渭河下游來水來沙變化的分析，針對現狀堤防過洪能力不足、控導工程少、河勢得不到控制和管理工程等方面存在的問題，提出應加大投入力度，完善防洪工程措施和非工程措施，加強管理，強化防洪減災意識，提高近期渭河下游防洪能力。 -
Incoming sediment variability analysis and sediment depositing calculation in the main river channel of the dongjiang basin
東江幹流河道來沙量變化分析及泥沙沉積量計算 -
Finally, by using of the mathematical model, it is calculated and predicted the effect of the different tongguan riverbed elevations as well as the different conditions of incoming water and sediment on the variance of the flood elevation and the tend of aggradation and degradation of the lower weihe river bed. it is answered quantitively the lessening extent of sediment silt and the decreasing extent of the flood elevation of the lower weihe river after 14 years on two different incoming water and sediment conditions with three different tongguan elevations, respectively 328m, 327m and 326m. these results supply important references to the planning of flood control and comprehensive regulations of the weihe river basin
最後用驗證后的數學模型對不同水沙系列、不同潼關高程（ 328m 、 327m 、 326m ）下渭河下游的沖淤趨勢和洪水位的變化進行了預測計算，從定量上回答了潼關高程從328m降至327m （相當于潼關高程降1m ）和潼關高程從328m降至326m （相當于潼關高程降2m ）時，渭河下游14年之後各河段的減淤程度以及不同流量級洪水位的降低幅度，這些成果對于渭河下游防洪治理規劃的制定具有重要的參考價值。
