  2. What ' s more, we put forward some experienced formulas on the basis of the cortical analysis. the result of the research show that by installing diffluent piers with low ridge, we can eliminate the root of oscillatiny water jump, perfect the energy dissipation effect of water jump, also, we can improve the flow condition of down - stream. the fact that the main flow of down - stream is in the middle, not only effectively lower the speed of the bottom flow in the ridge rear, alleviate the erosion to the river bed, but also avoid the heavy wave resulted from the main flow in the surface, thus improve the surface wave of down - stream obviously. we can work out the body style parameters of diffluent piers with low ridge according to the project flow condition and experience formulas, and then reckon the down - stream surface wave condition for the protected building of the down - stream bank

    研究結果表明：設置低坎分流墩后，消除了擺動水躍水舌擺動的根源，提高了水躍的消能效果，改善了下游水流流態。下游水體的主流在中部，既有效的降低了坎后水流底流速，減輕水流對河床的沖刷，又避免了主流位於表面導致波浪過大的結果，下游的水面波浪明顯得到削減。依據經驗公式，可根據工程水流條件設計出低坎分流墩的體型參數，進而估算出下游沿程的水面波浪，為下游岸邊的砌護提供依據。
  3. Then river width increased and the intensity of deep point lowing and bed material coarsening decreased and water level lowed continuously. so the bed form changed toward to u type. the bed regulation is realized through sediment silting in different parts in cross section during silting period and the deformation of bed form changed from broad u type channel to narrow and deep v type channel

    研究表明，河道在持續沖刷前期深泓點及水位下降與河床粗化同步發展，河床向v型發展；沖刷後期深泓點下降、河床粗化減弱，河道展寬增大，水位繼續下降，河床向u型發展；在以淤積為主時期的調整，是通過斷面不同部位的淤積來實現的，但都是由u型較大河槽向v型窄深小槽發展。
  4. 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。
