• Efficiency of permeable pile dike is closely related to water - sand ratio in upstream flow , direction of the coming flow and seepage rate . this paper investigates mechanism and effect of flow control and aggradation using hydraulic modeling and theoretical analysis . it is shown that suitable seepage rate can help aggradation and suitable coming flow direction can help to govern the flow trend
  研究结果显示，来流和来沙一定的条件下，透水率在适当的范围内有利于坝后缓流落淤，入流角在一定范围内对控导河势有明显作用，不同方案组合所对应的缓流落淤效果和控导河势作用具有一定的差异性。
• 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
  然后以实测资料为基础分析研究了三门峡建库前后潼关高程的变化规律以及渭河下游河道的冲淤演变规律，分析研究表明：建库前渭河下游主槽处于动态冲淤平衡状态，滩地处于微淤状态；建库后，渭河下游河道发生严重淤积主要是由于潼关高程的抬升造成的；潼关高程的抬升主要是由于三门峡水库的不合理运用造成的，近期不利的水沙条件加剧了潼关河床的抬升速度和渭河下游的淤积。
• 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
  最后用验证后的数学模型对不同水沙系列、不同潼关高程( 328m 、 327m 、 326m )下渭河下游的冲淤趋势和洪水位的变化进行了预测计算，从定量上回答了潼关高程从328m降至327m (相当于潼关高程降1m )和潼关高程从328m降至326m (相当于潼关高程降2m )时，渭河下游14年之后各河段的减淤程度以及不同流量级洪水位的降低幅度，这些成果对于渭河下游防洪治理规划的制定具有重要的参考价值。
