随着我国交通行业的快速发展,现浇混凝土预应力箱梁在道路建设施工过程中,由于其各种优点,该技术得到了大力推广运用。它的优点主要是所需建筑的高度比较小,整个建筑结构的刚度较大,并且结构比较轻巧,在抗震能力方面也比较强,最为重要的是整个施工过程简便灵活。还技术虽然具备了很多优点,但是在实际工程应用中,现浇混凝土预应力箱梁还是会收到各种不确定的因素的影响,比如恶劣的天气等自然因素以及人为操作不当等人为因素。在施工过程中,该桥型还普遍存在着一些质量方面的通病以及缺陷,不能够达到高质量的要求。此次主要是对其产生质量问题进行探究分析,并制定相应的解决措施,以确保其结构强度、耐久性符合施工要求。
With the rapid development of China's transportation industry, the precast concrete box girder cast-in-place in the process of road construction, due to its various advantages, the technology has been vigorously promote the use of. Its main advantage is the required height of the building is relatively small, the stiffness of the entire building structure larger, and the structure is relatively light, strong in seismic capacity, the most important thing is the entire construction process is simple and flexible. Although the technology has many advantages, but in practical engineering applications, cast-in-place concrete prestressed box girders or will receive a variety of uncertain factors, such as bad weather and other natural and man-made factors such as improper operation. In the construction process, the bridge type is also common to some common quality problems and defects, can not achieve high quality requirements. This is mainly to explore the quality of its problems and to develop appropriate solutions to ensure that its structural strength, durability in line with the construction requirements.
