flood control dam
解釋
防洪壩-
In the program, the effect of lamination placement, construction interval, elastic modulus change, thermal insulation change, surrounding temperature change, concrete creep and autogenous volume change on thermal stress are considered. and such temperature control measurement as water pipe cooling, heat preservation of the dam surface, the pouring temperature control, the overflow across the dam top during flood season can also be simulated by numerical method
該程序在編制過程中考慮了混凝土分層澆築、施工間歇、彈模變化、絕熱溫升過程、環境溫度的變化、混凝土徐變、自生體積變形等因素對壩體溫度場及溫度應力場的影響，同時也考慮了水管冷卻、壩體表面保溫、控制澆築溫度、施工汛期壩頂面過水等各種溫控措施的數值模擬。 -

On one hand, technological difficulty exists in determining the number and flood routing for dam system. on the other hand, for dam system security and stability, single dam ’ s designing should take flood control standard of dams, hinge composing, building sequence as well as years of filling up into account
一方面壩系整體調洪、數量的確定技術難度大，另一方面，小流域壩系中單壩的設計必須綜合考慮上下游壩的防洪標準、樞紐組成、建設順序、淤積年限等情況，才能保證壩系的安全和穩定。 -
Preliminary studies suggest that the mutual relations of the security, economic and risk should be adjusted and made into organic unity during determination of design flood standards for construction, the concepts on the cascade exploitation of the river should be transferred from flood control to flood management, the design flood standards for construction at the initial, middle and later stages of high dam projects should be driven up gradually according to reservoir capacity
初步研究認為，在施工洪水設計標準選擇時，應處理好安全、經濟和風險相互之間的關系，以達到三者有機的統一；在梯級開發河流上應實施從施工洪水控制到施工洪水管理的觀念轉移；高壩大庫工程的初期、中期、後期三個時段的施工洪水設計標準應根據庫容等指標逐步抬高。 -
Jahezi reservoir is located at the northwest arid area of china, the primary tasks of which are flood control land irrigation. it has been reinforced in 2003 so the discharge capacity and the safety of dam were increasing at large degree, which created the conditions to utilize the flood sufficiently by raising the limited water level
夾河子水庫地處我國西北乾旱區，主要承擔防洪及灌溉任務， 2003年除險加固完成後，水庫的泄流能力及大壩安全都有很大程度的提高，為水庫抬高汛限水位，實現洪水資源化創造了條件。 -
Mr. wang said the dam had improved flood control and navigation as well as helped china ' s environment by reducing reliance on coal
汪嘯風稱，三峽工程的防洪、發電、航運以及生態環境等綜合效益日益顯現。 -
Though the flood control engineering system improved the flood control standard and reduce the frequency of flood inundation and enlarger the protected area, but at the same time, the risk of dike broken and dam failed were added. moreover, people found that human living environment become worsen increasingly and the river ecosystem was destroyed
然而，在與洪水斗爭的過程中，人們發現雖然通過大規模的水利工程建設，提高了江河的防洪標準，減少了洪水泛濫的幾率，擴大了防洪保護的范圍，但同時也增加堤防、大壩潰決等的風險，而且人類發現生存環境日益惡化，河流生態系統被破壞等諸多問題。 -
The department also provides dam safety and flood control services, assists local water districts in water management and conservation activities, promotes recreational opportunities, and plans for future statewide water needs
