【摘要】：水閘是利用閘門擋水和泄水的中低水頭水工建筑物。水閘能夠雍高水位為城市供水，并且具有防洪排澇的作用，合理的設計水閘能夠形成水景觀效應，提高城市品位。本文以上饒信州樞紐為工程背景，研究了水閘樞紐工程的設計、施工以及服役期間定時安全檢測方面的內容。主要做了以下工作： （1）工程布置及主要建筑物設計。首先研究了壩址和壩型的選擇，在水文與工程地質的基礎上，綜合考慮樞紐布置、庫區(qū)浸沒、景觀效果以及工程投資效益等因素的影響，，選定壩址以及壩型；然后通過對工程不同布置方案的優(yōu)劣性對比，工程布置定為：右岸引水式電站+主河槽17孔深孔閘+左岸灘地20孔淺孔閘。最后研究了工程的泄流能力計算，閘墩頂高程確定，閘孔、消能防沖、電站廠房等主要建筑物的設計。 （2）工程施工。首先研究了信州樞紐工程的施工進度管理，包括臨時房建，風、水、電、通訊系統，混凝土生產及運輸系統和施工交通的總體布置；然后研究了地基開挖與處理、護坦及消力池、閘室、交通橋等主要項目的施工情況；最后研究了工程主要施工項目（包括導流、閘壩、壩肩及護岸、防洪墻混凝土澆筑等工程）的施工方案。 （3）閘墩結構動力檢測。為確保工程的安全運行，對信州樞紐工程閘墩結構進行了振動測試。通過對原型觀測信號處理，識別了結構振動的4階模態(tài)參數，并且建立了所測閘墩結構的有限元模型，進行有限元分析對比。最后對服役期間的水閘進行安全評定，結果表明：結構最大振幅、雙倍幅值和均方差均滿足要求；流激振動響應對人體的危害方面，該工程位于Meister感覺曲線的“相當的感覺到”區(qū)域。
[Abstract]:The sluice gate is a low and middle head hydraulic structure which uses gate to keep water and drain water. The sluice can supply water for the city with high water level and has the function of flood control and drainage. Reasonable design of sluice gate can form water landscape effect. Based on the background of Shangrao Xinzhou Project, this paper studies the design, construction and timing safety detection of sluice junction. The main work is as follows:. First, the selection of dam site and dam type is studied. On the basis of hydrology and engineering geology, the influence of key layout, reservoir area immersion, landscape effect and project investment benefit are comprehensively considered. The site and type of the dam are selected, and the advantages and disadvantages of different layout schemes of the project are compared. The engineering arrangement is as follows: the main channel 17 hole deep hole sluice on the left bank of the right bank diversion power station, the shallow 20 hole sluice on the left bank of the beach. Finally, the calculation of the discharge capacity of the project, the determination of the height of the pier top, the sluice hole, the energy dissipation and scour prevention are studied. Design of main buildings such as power plant. First, the construction schedule management of Xinzhou Hub Project, including temporary house construction, wind, water, electricity, communication system, concrete production and transportation system, and construction traffic layout are studied, and then the foundation excavation and treatment are studied. Finally, the construction scheme of the main construction projects (including diversion, gate dam, dam abutment and bank protection, concrete pouring of flood control wall, etc.) is studied. In order to ensure the safe operation of the project, the vibration test of the pier structure of Xinzhou Hub Project is carried out. By processing the prototype observation signal, the fourth order modal parameters of the structure vibration are identified. The finite element model of the measured pier structure is established and compared with the finite element analysis. Finally, the safety assessment of the sluice during service is carried out. The results show that the maximum amplitude, double amplitude and mean square deviation of the structure meet the requirements; The engineering is located in the "equivalent sense" region of the Meister sensory curve for the hazard of fluid-induced vibration response to human body.
