水利工程建设的目的是截留泄洪、调节水位、防旱排涝。从宏观角度来说,水利工程建设质量关乎区域经济发展与公众生命财产安全。然而,我国当前的小型水利工程建设质量监督管理工作仍存在诸多问题,且极大的制约了工程性能的发挥。在新形势背景下,为强化水利工程建设质量,应构建完善的工程建设质量监督体系,并采取行之有效的质量管理策略,确保水利工程发挥实际作用。
Abstract Traffic noise is the main environmental pollution of the elevated line. In order to prevent and control this noise, it is necessary to understand the spatial distribution of the noise. In this paper, the noise monitoring and data fitting of representative points near the Ningbo viaduct are carried out by means of the field test. By setting measuring points at different distances and heights perpendicular to and parallel to the elevated line, the spatial distribution law of noise near the elevated line is studied. The results show that: (1) The noise in the transverse direction of the bridge decreases in a logarithmic curve with the increase of the vertical distance between the measuring point and the viaduct; (2) The noise along the bridge decreases in a logarithmic curve with the increase of the vertical distance between the measuring point and the intersection; (3) The noise in the elevated direction first increases with the rise of the floor, reaching the maximum on floors 10-12, and the sound pressure on floors 12-20 is basically stable.
在水利工程中,生态护坡能够将河道以及周边植物覆盖率有效提升,实现水利工程河道水域生物全方面发展。河道生态护坡施工具有多种功能,主要是生态功能、防洪功能和景观功能,其主要技术形式包括原型护坡施工技术、土工材料固土施工技术、三维植被网护坡施工技术,这些技术形式有效应用能够将河道护坡防洪效果全面提升。基于此,文章就水利工程河道生态护坡施工要点展开分析和探讨。
幕墙开启扇锁点的理论分析包含锁点荷载和锁点承载力的取值分析,而锁点安全的实现需要同时保证锁点荷载和承载力的取值理论假设能够被实践.论文指出,通过对开启扇整体建模分析,充分考虑杆件的计算模型对锁点荷载的影响,可以求得最真实的锁点荷载;通过对锁点材质、厚度、截面的材料力学理论分析,以及与试验数据的对比,可以选取合适的锁点承载力取值;通过可操作、有效的方法检测锁点实际安装是否符合理论分析的假设,可以最终保证幕墙开启扇锁点的安全.
