  1. The analyzed results are as follows : the late 1960 ' s cutoff of riverbends increased both the runoff amount and the sediment transport amount of the lower reach of jingjiang river, while the sediment deposition decreased in the lkngting lake area ; after the mid 1980 ' s, both the middle reach of yangtze river main stem and the dongting lake occurred a trend of decreasing annual sediment transport as a result of decreasing sediment releasing from the upper reach of yangtze river ; and in the recent 3 years ( 2003 - 2006 ), the three gorges reservoir first impoundment additionally reduced the sediment concentration in the middle reach of yangtze river flow with a long time, so a distance would be quite long for suspended sediment recovery, but the distance for bed - material load of suspended sediment recovery would be quite short

    分析結果表明: 20世紀60年代下荊江裁彎后,三口(松滋口、太平口、藕池口)分流分沙減少,下荊江徑流和輸沙相應增加,洞庭湖泥沙淤積減少; 80年代中期以後,長江中游幹流及洞庭湖出口的年輸沙呈減少趨勢,城陵磯至武漢床由淤積轉為趨向沖淤平衡;三峽工程初期運用后,長江中游含沙沿程恢復距離較長,但床沙質部分恢復距離相對較短。
  2. ( 6 ) conclusion was obtained by the analyzing the mechanics environment and the stability of the lanslide on the right bank after the dam built : the value of the rock mass stress increased and the tensile stress region obviously reduced, the direction of the principal stress was unchangeable the dam and the landslide were stable under the dangerous condition ( the reservoir and at the same time the earthquake was viii ), but when the water lever suddenly fell and did not think of other force, safe factor evidently reduced, the dam and the landslide will be destroyed under the most dangerous condition ( the water lever suddenly fell and at the same time the earthquake was vi ) ; the stability of the landslide will be destroyed by the horizontal thrust under the most dangerous condition or ; the physical and mechanical parameter will be reduced due to long period filter, the landslide will be destroyed too

    ( 6 )建壩工程荷載條件下谷巖體力學環境分析及右岸古滑坡體的穩定問題分析得出:建壩后谷的巖體應力值明顯增高,同時左岸的張應力區的范圍及值明顯減小,主應力的方向依然與模型的底邊界垂直;大壩建成后逐漸以及同時考慮本區最強地震力的作用等各種不同的工況條件時,滑坡體及壩體總體上仍處于穩定狀態;位驟降時,在未考慮其他外力作用的情況時,滑體的安全系數將顯著降低。若考慮位驟降及本區最大地震力的共同作用,壩體將在滑坡體下滑推力的作用下產生破壞;建壩后平推力對右岸古滑坡體穩定性的影響分析可以看出,在最危險的工況條件下,壩體及滑坡體也將處于臨界狀態;在長期滲透變形的作用下,由於滑帶的物理力學參數的降低而有可能導致壩體失穩破壞。
  3. Based on the analyses of the flow and sediment characteristics and evolution trend of the river bed of the fuling reach in the yangtze river before and after the impoundment of the three gorges reservoir, the water level, velocity variation and influenced range in the fuling reach before and fifty years after the operation of the three gorges reservoir with the construction of the fuling dock and four discharge combinations are calculated by using a two - dimensional flow mathematic model
