General Design Layout of Datengxia Ship Lock by LI Yawen, CHEN Guihua

“…The Datengxia hydro project is a key project to open the 100-million-ton golden waterway of the Xijiang River,with high navigation requirements for the dam-site reach and a huge freight volume.The general design layout of the navigation structure ship lock plays a vital role in the layout scheme,freight volume,operation management,and investment of the whole hydro project.For the general design of the ship lock, the position of the ship lock is first selected according to the topographical and geological conditions of the project area and the layout requirements of the hydro project.On this basis,this study designs the lock head,lock chamber,water conveyance system,upstream and downstream approach channels,entrance area and connecting section,anchorage to be locked,etc.Additionally,the structural dimensions of the water conveyance system and rectification measures in the entrance area are optimized according to the model test results.The Datengxia ship lock has reached the highest level of ship locks built at home and abroad in terms of the scale,water head,water-level variation amplitude conditions,and hydraulic index requirements.Its general layout can provide a certain reference for the design of large-scale and high water-head ship locks.…”

Study on Calculation of Cross-section Area of River Based on Analysis Method of Mid-point Distance Section by DANG Xicheng, LUO Yi, WANG Haiyan, LI Rong

“…The cross-section area is one of the key factors in flow measurement by velocity area method,and its calculation accuracy is directly related to the accuracy of flow measurement.Due to the complexity and diversity of the river section,the existing software algorithm cannot accurately judge the real position of the river flow through the large section data,resulting in the extraction error of the range of the cross section and the vertical depth.Therefore,with computer programming technology,this paper puts forward the analysis method of river mid-point distance section for identifying the position of river flow and judging the type of section,such as single section and compound section,extracting the water's edge and vertical line,and calculating the area.The application shows that the software can accurately analyze the river flow position under different hydraulic conditions by this method,and calculate the river cross-section area,achieving the purpose of algorithm design.This method can be widely used in automatic hydrological detection equipment or hydrological analysis software to improve the analysis ability of the equipment or software for cross-section flow area of river.…”

Exploration and Practice of Annual Safety Report Regulation for Long-Distance Water Diversion Projects by HU Jiang, MA Fuheng, SHENG Jinbao, DAI Zhanqiang, LI Shuncai, FU Youqun

“…Long-distance water diversion projects are important strategic infrastructure to optimize the patterns of water resource allocation,which are characterized by long distances,many hydraulic structures,complex geological and environmental conditions,and high maintenance requirements.The long-term safe operation of these projects has been highly concerned.The annual safety report of these projects is an effective means to grasp the engineering status in a timely and dynamic manner.On the basis of the characteristics of these projects and the discussion on the existing basis and compilation principles of annual safety reports,the organization and implementation of the main work in annual reports,such as safety inspection,safety detection,and safety assessment,are explored,and the regulation of an annual safety report is proposed.According to the practice of the first annual safety report on the central route of the South-to-North Water Diversion Project,the key contents of the annual safety report,including safety inspection,safety detection,and safety monitoring,as well as operational management contents such as dispatching operation,maintenance,safety production,and emergency management are briefly introduced.Finally,the experience,understanding,and difficulty of annual safety report compilation are summarized.The successful application of the annual safety report in the central route project can provide a reference for similar projects.…”
