  2. There is sharp gradient in top and small gradient in bottom. the ability of removing flood is high in top and it is small in bottom correspondingly. sediment silt up continually, so the bed of river is jacked up year by year and become the famous river on land

    由於泥沙含量高,現行河道已行水140餘年,山東段河床上寬下窄,坡度上陡下緩,排洪能力上大下小,在泥沙淤積作用下,河床逐年抬高,成為世界上著名的地上「懸河」 。
  3. However, there are much silt, silty clay, and silt - and - sand bed in the highway grounds of many provinces and cities

    我國許多省市的公路地基中大量存在著淤泥、淤泥質粘土、淤泥混砂層。
  4. However, there are much silt, silt clay, and silt - and - sand bed in the highway grounds of many provinces and cities. if expressways are built on these grounds without improvement or managed improvement, the quality of roads will fall even destroy

    我國許多省市的公路地基中大量存在著淤泥、淤泥質粘土、淤泥混砂層,若不經過處理或處理不當,會引起道路質量的降低甚至破壞,因此,必須加強高速公路軟基處理的研究。

  6. 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。
