The results indicated that with the change of water and sand condition and the altitude of tongguan and the development of the industry and agriculture in recent decades, the water environment of wei river had changed largely, which were shown as follow : annual runoff and seasonal flood decreased sharply ; water stream of large discharge decreased and the range of runoff decreased greatly ; sediment load per year decreased generally, sediment concentration of water increased, and the sand silting up was serious ; water channel swung and shrank, and water regime deteriorated ; frequencies of big floods decreased obviously, and hyper concentrated flood increased obviously ; water levels of the same runoff rose universally, and the frequencies of the floods increased and aggravated ; water pollution was very serious
結果表明，近期隨著水沙條件、潼關高程等的變化及工農業的發展，渭河的水環境發生了巨大變化，表現在年水量及汛期水量銳減；大流量級水流出現次數減少，水量減少幅度大；年輸沙量總體減少，河水含沙量增大，泥沙淤積嚴重；河道向擺動型發展，河道萎縮，河勢惡化；大洪水發生的次數顯著減少，高含沙小洪水明顯增多；同流量洪水位普遍抬高，洪災發生次數增加，洪災加重；水質污染極為嚴重。 -

Complicated hydrologic and geographic conditions, and the large scale of the xiaolangdi hydraulic project on the yellow river are introduced briefly. three desilting tunnels are designed to meet the requirements of flood control, sediment discharge and runoff regulation. according to the performance requirements of desilting tunnels, the tunnel lining down - stream of the grouting curtain is designed to be post - tensional prestressed lining. on the basis of investigation and research, experiements and analysis, the unbonded prestressing system is used. it is the largest unbonded prestressed tunnel lining project in the world, and the first one in china
簡介黃河小浪底水利樞紐復雜的水文、地質條件以及龐大的工程規模.該樞紐設計有3條排沙洞，擔負著泄洪、排沙、調節徑流和保證進水口不被泥沙淤堵的任務.根據排沙洞的水庫運用要求，灌漿帷幕下游排沙洞洞身段設計為混凝土后張預應力隧洞.通過大量的調研、試驗、分析論證，在施工前確定該預應力方案選用無粘結預應力系統，成為目前世界上規模最大的無粘結預應力隧洞襯砌工程，在國內尚屬首例 -
Based on analyzing discharge data in guide, xunhua, tongren hydrologic station and river course character, propagation time of different discharge in different river course is presented, and prediction period of interval flood, main stream flood during construction and operation period are acquired
通過對貴德、循化、同仁水文站流量資料以及河道特性的分析研究，得出不同流量在不同河道上的傳播時間，歸納出區間洪水和幹流洪水在施工期和運行期的預見期。 -
To reasonably plan out the scheme for the sewage discharge outlets of changshu fluorine chemical industry project, the article makes an ana lysis on the water environmental features of changshu section of the yangtze riv e, develops a plan two - dimensional model of coupled water flow - quality for its co mplicated underwater topography and stream flow - field. the model is relatively ac curate and practicable to predict the impact of scheme on water quality. varied s chemes have been compared and demonstrated from multiple angles, such as flow fie ld, impact assessment of water quality, technique and economy. the scheme of sewage discharge outlets away from the shore is recommended. the article provides a sci entific basis for the engineering design and envirommental management of the pro ject
為合理確定常熟氟化工項目排污口布置方案，本文在分析長江常熱段水環境特徵的基礎上，針對其復雜的水下地形和水流流場，建立了較為準確和實用的平面二維水流水質耦合數學模型，預測計算了三套方案污水對重點保護水域影響程度和范圍，並從水流流場、水質影響評價、技術經濟多角度對方案進行了比較論證，最終推薦污水江中排放的方案，為項目的工程設計和環境管理提供了科學依據。 -
