摘　　要：青山冲水库工程为贵州省重点水源项目之一,是一座以灌溉、供水为主的中型水利工程。青山冲水库工程进水口交通桥承担着金属结构及机电设备安装通行的重要作用,具有跨度大,承受荷载大等特点。工程中使用的贝雷桥是使用高强度钢材制成的轻便标准化桁架单元结构,由横梁、纵梁、桥面板、桥座及连接件等组成,安装便捷,节省工期。通过贝雷桥的设计、施工、试验、验收及备案等方面全面阐述贝雷桥在青山冲水库工程中的设计及应用情况,具有一定的经济效益及推广价值。The Qingshanchong Reservoir is one of the key water source projects in Guizhou Province,serving primarily as a medium-sized water conservancy project primarily for irrigation and water supply.The inlet access bridge of the Project plays a crucial role in installation and transportation of metal structure and electromechanical equipment,characterized by large span and high load-bearing capacity.The Bailey bridge used in the project is composed of lightweight,standardized truss units made of high-strength steel,along with components such as crossbeams,longitudinal beams,deck panels,bridge seats,and connectors.It is easy to install,thus saving construction time.This paper comprehensively discusses the design,construction,testing,acceptance,and documentation of the Bailey bridge in the Qingshanchong Reservoir Project,highlighting its economic benefits and potential for wider application.
